Description

ALLOCATING RESOURCES IN AN AUTONOMIC SENSOR NETWORK ECOSYSTEM

FIELD OF THE INVENTION

The present invention generally relates to an autonomic sensor network ecosystem. Specifically, the present invention relates to a method, system and program product for deploying resources, allocating resources and addressing threats in the autonomic sensor network ecosystem.

BACKGROUND OF THE INVENTION

In traditional computer-based storage systems, data is typically stored in sophisticated systems with layers of protections, backups systems, and encryption algorithms. The rise of wireless technologies and peer-to-peer (P2P) delivery systems is forcing the IT industry to decentralize infrastructure and it's applications. Specifically, static physical infrastructures are being replaced with remote virtual environments that make traditional network, data, and applications obsolete. To this extent, even hardware supporting the traditional infrastructure is not scalable and proportional to deliver and meet the demands of P2P environment requirements. As such, conventional IT concepts are changing in an attempt to adopt a new model that provides a more scalable, and secure virtual infrastructure.

The above-incorporated patent applications all take various steps towards providing such an infrastructure. For example, U.S. Patent Application No 10/856,684 avoids data loss by providing a wireless sensor network in which a plurality of peers/motes/nodes are interconnected (e.g., on a peer-to-peer basis) . To store a data set within the network, the data set is broken up into data components, which are then stored among the nodes. Storage of the data components typically occurs by following a routing path through the network according to a routing table or the like. As the path is followed, the data components are stored among the nodes. Other examples of sensor based detection systems are described in US Patent No. 6,169,476 Bl, and US Patent No 6,293,861 Bl.

Under U.S. Patent Application No. 10/946,714, a sensor network comprising a plurality of peer-to-peer nodes is provided. Each node in the network includes, among other things, a sensor for detecting environmental factors. When a potential failure is detected within a node, the node will query its neighboring nodes to determine whether they have the capability to store any data component (s) currently stored within the potentially failing node. Based on the querying, the data component (s) in the potentially failing node are copied to one or more of the neighboring nodes. Thereafter, details of the copying can be broadcast to other nodes in the network, and any routing tables that identify the locations of data components stored throughout the sensor network can be updated.

Under U.S. Patent Application No. 10/972,610 , an autonomic sensor network ecosystem is provided. Such autonomic sensor network ecosystem includes: (1) a set (e.g., one or more) of sensor networks for storing data components; (2) a set of sensor collector information gateways in communication with the sensor networks; and (3) a set of enterprise gateways and storage hubs (hereinafter referred to as enterprise gateways) in communication with the micro grid gateway.

As advanced as these technologies have become, there still exists a need for a further evolution of the autonomic sensor network ecosystem. Specifically, a need exists for a method, system and program product for deploying (e.g. resources), allocating and addressing threats for an autonomic sensor network ecosystem.

Detailed description of the invention

I . General Description

As indicated above, the present invention provides a method, system and program product for deploying, allocating and addressing threats for an autonomic sensor network ecosystem. Specifically, under the present invention, the autonomic sensor network ecosystem includes a set (e.g., one or more) of sensor networks each having a set of sensor peers and at least one super peer; a set of micro grid gateways; and a set of enterprise gateways. Each micro grid gateway is typically adapted to receive requests from a sensor network, an enterprise gateway, and/or another micro grid gateway. Moreover, each micro grid gateway includes a request broker for receiving the requests; a request queue manager for queuing the requests; a scheduler for scheduling the requests; and a resource manager for monitoring the set of sensor networks.

Referring now to Fig. 1, an autonomic sensor network ecosystem

(ecosystem) 10 according to the present invention is shown. As depicted, ecosystem 10 includes sensor/peer network (s) /micro grids 12A-B (collectively referred to as micro grid node 20) , a micro grid gateway 14 and an enterprise "grid" gateway 16. It should be appreciated that two sensor networks 12A-B, one micro grid gateway 14 and one enterprise gateway 16 are shown for illustrative purposes only. However, ecosystem 10 could have any quantity thereof. Communication between sensor networks 12A-B, micro grid gateway 14 and enterprise gateway 16 can occur via a hardwired connection and/or a wireless connection. To this extent, communication typically occurs over a network such as the Internet, a local area network (LAN) , a wide area network (WAN) , a virtual private network (VPN), etc. Conventional network connectivity, such as Token Ring, Ethernet, WiFi or other conventional communications standards could be used. Still yet, connectivity could be provided by conventional IP-based protocol. In this instance, an Internet service provider could be used to establish interconnectivity.

In general, enterprise gateway 16 is a cluster of components that interact with micro grid gateway 14 and help balance the load of transactions being requested to or from the enterprise grid resources. Enterprise gateway 16 has the ability to reroute transactions appropriately, perform types of computational transactions, and smart prioritization of transaction requests. Enterprise gateway 16' s architecture is typically ad-hoc, scalable and virtualized. Micro grid gateway 14 similarly is also a cluster of components that interact with the enterprise gateway 16 and the sensor networks 12A-B. It handles the processing of requests for computational transactions from either the sensor networks 12A-B or enterprise gateway 16, and allocates appropriately the resources to perform the task. As will be further described below, micro grid gateway 14 generally includes a request broker 22, a request queue manager 24, a scheduler 26, and a resource manager 28. The architecture, similar to the enterprise gateway 16, is ad-hoc, scalable and virtualized. Sensor networks 12A-B can be a variety of components that have computational abilities. It can also serve as smart sensors that provide monitoring and security features as outlined above. The nodes/peers 18A-B of sensor networks 12A-B are able to initiate job transactions to micro grid gateway 14 and also to enterprise gateway 16. The architecture for sensor networks 12A-B is ad-hoc, scalable, and virtualized.

As further shown in Fig. 1, sensor networks 12A-B each generally include a set of peers 18A-B comprised of a set of sensor peers (e.g.,

SP1-SP4) and a set of super peers (SP/R1 and SP/R2) . As will be further described below, when ecosystem 10 is deployed and allocated, a data structure can be broken down into components and stored within the sensor peers SP1-SP4 of sensor networks 12A-B. Sensor networks 12A-B may be implemented in an ad-hoc or mesh network that comprises either a full mesh or partial mesh topology. In a full mesh topology, each peer 18A-B is in communication with each other peer 18A-B. In a partial mesh topology, each node is not necessarily in communication with the other nodes. While the invention is typically implemented in a wireless environment, it is recognized that some or all of the communications could be implemented using a wired technology.

In general, (as described below in conjunction with Fig. 2) peers 18A-B are configured to broadcast information (e.g., state or status information) to one another. Moreover, as will be further described below, peers 18A-B are configured to bond together (e.g., via JOIN and GATHER requests) to form sensor networks 12A-B. Super peers SP/R1 and SP/R2 are configured to manage sensor networks 12A-B, and to communicate with and/or relay information to micro grid gateway 14. Such communication/relaying can occur using push or pull (e.g., query) techniques .

Under the present invention, micro grid gateway 14 includes a micro grid request broker 22 for receiving requests from sensor networks 12A-B, enterprise gateway 16 and/or other micro grid gateways 14; a request queue broker 24 for queuing the requests, a scheduler 26 for scheduling the requests for communication between the sensor networks 12A-B and the enterprise gateway 16; and a (micro grid) resource manager 28 for monitoring sensor networks 12A-B and allocating resources based on the monitoring. In monitoring sensor networks 12A-B, resource manager 28 is operable to monitor a resource state, an attribute lifecycle, and events for sensor networks 12A-B. Resource manager 28 is also operable to provide for event notification, query sensor network 12A-B for attributes, and discover resources of sensor networks 12A-B.

In addition to depicting the actions and roles of the micro grid gateway 14, Fig. 1 shows how resources from the sensor networks 12A-B broadcast their availability to resource manager 28 (e.g., in either a publish and/or subscribe mode) . To this extent, resource manager 28 can also trigger state request polling as described in more detail below. Still yet, Fig. 1, depicts the types of job submissions and requests. Specifically, as indicated above, requests can be submitted to micro grid gateway 14 by the sensor networks 12A-B or enterprise gateway 16. Processing of such requests can be broken into job transactions that are allocated to appropriate resources in sensor networks 12A-B and/or enterprise gateway 16.

Referring to Fig. 2, the broadcasting of resource state information under the present invention is shown. Specifically, SP/R1, SP/R2, and SP/R3 collect information from surrounding peers and relate such information to micro grid gateway 14. This information communication can occur via periodic querying (e.g., pulling) or broadcasting (e.g., pushing) from SP/R1, SP/R2, or SP/R3 about the status of monitoring from that grid. In any event, micro grid gateway 14 will communicate such information to enterprise gateway 16 for analysis. If action needs to be taken, messages (e.g., via SMS or SIP) can be sent directly to peers SP1-SP4, and SP/R1, SP/R2, and SP/R3 to conduct further actions.

Referring now to Fig. 3, a more detailed stack/layer diagram of ecosystem 10 is shown. As shown, each peer includes the following layers/systems/services: (1) awareness, discovery and broadcast 23; (2) request and event 25; (3) application and data 27; (4) security stack credentials and encryption 29; (5) management 30; (6) network transport 32; (7) power management 34; (8) sensor 36; and (9) super peer/relay 38.

In general, awareness, discovery and broadcast system 23 allows peers to communicate or exchange information with one another, and bond together to form a network. As discussed in the above cross-referenced patent applications, this process can include JOIN and GATHER and requests being exchanged. Request and event services 25 provide for detection and administration of events within the sensor network. Application and data service 27 provides for the storage of data components within the peers. To this extent, application and data service 27 stores and relocates/copies data components as described in the above-incorporated patent applications. Security, stack, credentials and encryption key layer 29 provides the necessary security for the peers. Specifically, since data components will be stored therein, security is provided. Management service 30 provides for the configuring and administration of peers. Network transport layer 32 includes a passive layer and an active layer. The passive layer is used for passing or "hopping" data from one peer to another. The active layer is utilized for communicating data gathered or generated by the peer itself. Power management layer 34 may comprise an energy supply such as a solar cell.

Sensor layer 36 is for sensing environmental changes (e.g., vibration, wind, chemicals and temperature) and may comprise any type of sensor or sensors that measure some environmental stimuli, including physical, chemical, or biological changes. To this extent, sensor layer 36 may collect, process and store sensed data.

As further shown, each peer 18A-B includes super peer/relay services 38. Under the present invention, each peer 18A-B is capable of becoming a super peer within the sensor network. The general role of the super peers is to gather information from the other peers, maintain a table of such peer information, and relay/communicate with micro grid gateway 14. In the event a super peer fails, another peer within the sensor network can be "promoted" to super peer status.

It should be understood that each peer 18A-B could include other systems/layers/services not depicted herein. Such systems/layers/services are shown and described in the above-incorporated patent applications. For example, each peer 18A-B could also include a local or global routing table for indicating the locations of data components stored within the sensor network, and an update system for updating the local and/or global routing tables as data components are copied/relocated among the peers (e.g., in the event of potential failure of a peer) .

As further shown in Fig. 3, micro grid gateway 14 includes: (1) business process rules 40; (2) sensor network management interface 42; (3) message queue 44; (4) security stack 46; and (5) network transport layer 48. Business process rules 40 are used to guide decision-making and the general functionality of micro grid gateway 14 (e.g., selecting a peer as a super peer) . Sensor network management interface 42 is the interface or communication channel between micro grid gateway 14 and the sensor networks. Message queue 44 is a queue for storing messages and communications received from and/or communicated to the sensor networks and enterprise gateway 16. Security stack 46 provides security for micro grid gateway 14, while network transport layer 48 allows for the passing/hopping of data components.

Each enterprise gateway 16 includes: (1) security layer 50; (2) message hub 52; (3) data store 54; (4) management service 56; (5) enterprise grid service 58; and (6) business process rules 60. Security layer 50 provides security for enterprise gateway 16. Message hub 52 handles all communications received on enterprise gateway 16. As shown in Fig. 3, a single enterprise gateway 16 could hold communication with multiple micro grid gateways 14. Message hub 52 helps to track all such communications. Operational data store 54 provides storage for data components. Management service 56 provides for the management of enterprise gateway 16. Enterprise grid service 58 provides for the management of ecosystem 10 as a whole. Business process rules 60 are used to guide decision-making and the general functionality of enterprise gateway 16 (e.g., recommending a course of action in response to an event within the sensor network) .

As mentioned above, ecosystem 10 can be a multi-network environment.

An example of this is shown in Fig. 4. Under the present invention, ecosystem 10 can include any quantity of sensor networks 12A-D, micro grid gateways 14A-D and enterprise gateways 16A-D. This provides optimal redundancy/resiliency in the event of failure of one or more components. As further shown, communication can occur between any of the components.

II . Deployment and Allocation

Given the above description of ecosystem 10, the process of deploying and allocating resources in ecosystem 10 will now be further described in conjunction with Fig 5. In order to form sensor networks 12A-B, the sensor peers and super peers within sensor networks 12A-B will first broadcast peer information (e.g., via broadcast layer 23 of Fig. 3) to one another. Such information includes their roles, availabilities, locations and functionalities. Upon such communications "bonding" takes place and sensor networks 12A-B are formed.

In forming sensor networks 12A-B in this manner, the JOIN and GATHER teachings described in the above-incorporated patent applications can be followed. For example, when a peer is first powered up, its communication can be limited to a JOIN broadcast message, which essentially says, "I'd like to join a network." Thus, when sensor networks 12A-B are first activated, each peer could only broadcast a JOIN, and will not receive a response until an endpoint gets involved. Endpoints are initialized with the capability of responding to JOIN broadcasts. Namely, an Endpoint will answer all JOIN broadcasts that it can detect with a GATHER response. Thus, an Endpoint recognizes JOIN broadcasts from neighboring peers, and responds with a GATHER. As soon as a peer recognizes a GATHER, the peer can become a member of sensor network 12A-B and can stop broadcasting the JOIN. Thus, initially, the sensor networks 12A-B are comprised of the Endpoint and the Endpoint' s neighboring peers. Neighboring peers may, for example, be defined as a set of nodes that can communicate with each other.

As soon as a peer establishes itself in sensor networks 12A-B, the peer can switch to a GATHER broadcast to gather its own neighbors. Thus, the cycle repeats itself, with each peer broadcasting a JOIN getting picked up as a neighbor of another nearby gathering peer (or endpoint) . Again, whenever a peer becomes a neighbor within the network, it switches from JOIN to GATHER. Very quickly, all peers will become another peer's neighbor. As soon as a peer becomes a neighbor, it can collect data and send it to a neighbor. The neighbor will pass the data to its neighbor, etc., until the data makes its way back to the Endpoint. Network redundancy is established by allowing each peer to have many neighbors within the network in a manner described below.

After a short period, the entire sensor network 12A-B is established. At some point, when a peer is no longer receiving JOIN requests, a peer can determine that the sensor network 12A-B is formed. Each peer will still send out GATHERS, but at a much lower frequency, since the only new peers that would join are nodes that, for example, replace broken peers. In forming sensor networks 12A-B, super peers will be appointed (e.g., by micro grid gateway 14A-D) from among the peers.

In any event, once sensor network 12A-B has been formed, the super peers will create and manage a table of "peer" information, which is shown below in greater detail.

Sensor Mac ID Role Resource Location

SPl Sensor Peer / Super Peer 100% N

SP2 Sensor Peer / Super Peer 100% W

SP4 Sensor Peer / Super Peer 100% S

SP/R1 Sensor Peer / Super Peer 100% NE SP/R3 Sensor Peer / Super Peer 100% E

As shown, for each peer, the table includes an identifier (e.g., a MAC ID) , a role, a resource availability and a relative location within sensor network 12A-B. As this process is occurring, micro grid gateway 14 will broadcast gateway information similar to the peer information to one another, and bond together. Micro grid gateways 14A-D will also create a table "gateway" information that is shown below:

Micro Grid Gateway Role Resource Location

Gateway A Gateway 100% N

Gateway B Gateway 100% E

Gateway D Gateway 100% S

As shown, for each micro grid gateway 14A-B, the table identifies an identifier, a role, a resource availability and a relative location within the ecosystem.

Once these first two steps are completed, the super peers within sensor networks 12A-B will communicate with micro grid gateways 14A-D. During this communication the peer and gateway information (e.g., tables) will be exchanged. During the communication, micro grid gateways 14A-D can query the super peers (or be "pushed") to obtain the peer information. In either event, when this is complete, micro grid gateways 14A-D will communicate peer information and micro grid information to enterprise gateways 16A-D, which will build and maintain a table of enterprise information containing the same. At this point, ecosystem 10 has been deployed and allocated. As such, it can be used to safely store data components (as indicated in the above-incorporated patent application) .

Ill . Illustrative Scenarios

Figs. 6-14 will now be used to describe two illustrative scenarios in which requests are handled under the present invention. Specifically, Figs. 6-10 correspond to a first illustrative scenario involving ecosystem 10. Referring first to Fig. 6, in a first step, a micro grid gateway 14A-D requires an analytical computation and sends out a request through its grid request broker to enterprise gateway 16A-D for computing resources available. In a second step, micro grid gateways 14A-D poll their sensor networks 12A-D to obtain available resources. In the third step shown, SP/R1 and SP/R2 of sensor networks 12A-D poll their respective peers to analyze available resources. The process is continued in Fig. 7 where in a next step SP/R1 and SP/R2 of sensor networks 12A-B relate to micro grid gateways 14A-B that all sensor peers, including themselves, are available resources with specific details, such as computational availability, memory resources, etc. Next, in this illustrative scenario, SP/R1 and SP/R2 of sensor network 12C relate to micro grid gateway 14C that SP2 & SP4 are available resources with specific details, such as computational availability, memory resources, etc., while SPl and SP3 are not active. As this is occurring, SP/R1 and SP/R2 of sensor network 12D relate to micro grid gateway 14D that SPl, SP3, SP4, and themselves are available resources with specific details, such as computational availability, memory resources, etc., while SP2 is not active.

Thereafter, an enterprise table is created depicting resources as follows:

Grid A: All active

Grid B: All active Grid C: SPl & SP3 not active

Grid D: SP2 not active

Referring now to Fig. 8, the illustrative process is continued. In a next step, SP/R1 and SP/R2 of sensor network 12A detect failures in SPl and SP2 and sends out a request for additional computing resources to replace them. As a result, micro grid gateways 14B-D for sensor networks 12B-D poll their respective SP/R1 & SP/R2 for resources available to perform additional computing capabilities. Assume in this example that sensor networks 12B and 12D respond with resource availability, while sensor network 12C has no resource availability.

Turning to Fig. 9, micro grid gateways 14B and 14D broadcast the availability of their respective sensor networks 12B and 12D. SP/R1 and SP/R2 of sensor 12A receive this information, confirm utilizing such resources, and broadcast internally to active peers. Thereafter, enterprise gateway 16A updates the table of enterprise information to reflect the relative statuses based on the re-allocation as follows:

Grid A: SP2 & SPl not active Substitute Utilizing SP4 from Grid B

Substitute Utilizing SPl from Grid D

Once the table is updated, the local active sensor peers in sensor network 12A communicate to the respective sensor peers from sensor networks 12B and 12D for any dependent computational requirements. The illustrative scenario is finalized in Fig. 10, in which each sensor network 12A-D completes its analytical computation and sends back corresponding information to enterprise gateways 16A-D to complete a correlation and integration for a final computation.

As can be seen in the scenario illustrated in Figs 6-10, communication between sensor networks 12A-D and enterprise gateways 16A-D flowed through micro grid gateways 14A-D. Furthermore, as illustrated, communication can occur between micro grid gateways 14A-D under the present invention.

Figs. 11-14 illustrate a second scenario under the present invention, in which a threat to a sensor network is detected, and in which communication occurs directly between sensor networks 12A-D and enterprise gateways 16A-D. Referring first to Fig. 11, sensor peers in sensor networks 12A-B detect foreign chemical agents, and send a request to their respective micro grid gateways 14A-B for analysis. If the resources at the micro grid gateways 14A-B are unable to process and analyze the information, the requests are then forwarded to enterprise gateways 16A-B for further analysis. Assume in this example that the micro grid gateways 14A-B are in fact unable to process the requests. In such a case, enterprise gateways 16A-B will receive the original requests from sensor networks 12A-B, and summon the analytical processes needed to analyze data gathered.

Referring now to Fig. 12, it is assumed that the analytical processing performed by enterprise gateways 16A-B conclude that a hazardous environment exists in sensor network 12A, and sends an immediate request for the sensor peers to deploy counter biomaterials to neutralize the environment. Conversely, the analytical processing performed by enterprise gateway 16B concludes that a safe environment exists in sensor network 12B despite the foreign chemical agent, and sends a request for the sensor peers to continue monitoring and return data back for analysis.

In Fig. 13, it can be seen that the sensor peer in sensor network

12A has contained the foreign biochemical agent but continues to send data to the enterprise gateway 16A for analytical processing. This allows enterprise gateway 16A to continue analyzing the real time data retrieved to make sure that the foreign chemical agent has been neutralized. As this is occurring, assume that the applicable sensor peer in sensor network 12B continues to send data to the enterprise gateway 16B for analytical processing to request the continued analysis of the real time data retrieved. This is to ensure that the passive foreign chemical agent is not a threat to sensor network 12B.

Lastly, in Fig. 14, the analytical processing of enterprise gateways 16A-B conclude, based on the data gathered, that the foreign chemical agents have been neutralized. However, enterprise gateways 16A-B continue to request data for monitoring the environment. If such monitoring concludes that there is still a threat of the foreign chemical agent, deployment of agencies are required for the next level neutralization. As further shown, the analytical process of enterprise gateway 16B still concludes that a safe environment exists in sensor network 12B.

Nevertheless, enterprise gateway sends a request for the sensor peers to continue monitoring and returning data to enterprise gateway 16B for analysis .

However, if micro grid gateway 14 comprises a handheld device or the like, it is understood that one or more external devices 108 (e.g., a display) and/or storage system(s) 60 could be contained within micro grid gateway 14, not externally as shown. It should also be understood that sensor network 12 and enterprise gateway 16 will likely include computerized components similar to micro grid gateway 14.

In another embodiment, storage system 110 includes data distributed across, for example, a local area network (LAN) , wide area network (WAN) or a storage area network (SAN) (not shown) . Although not shown, additional components, such as cache memory, communication systems, system software, etc., may be incorporated into micro grid gateway 14. Shown in memory 102 of micro grid gateway 14 is micro grid gateway program 112, which is a software program that will provide the functions of the present invention, and which includes micro grid request broker 22 for receiving requests from sensor network 12, enterprise gateway 16 and/or other micro grid gateways 14; request queue broker 24 for queuing the requests; scheduler 26 for scheduling the requests for communication between the sensor network 12 and the enterprise gateway 16; and (micro grid) resource manager 28 monitor sensor network 12 and allocating resources based on the monitoring.
