Abstract

System enabling the dynamic deployment and/or the creation of tasks within a network comprising at least one master node (0) and several sensor nodes Ni having limited processing capacities, the network supporting a communications software application exposing the functionalities of each sensor node as services on the said network and a mediation mechanism allowing communications between the services of various sensor nodes of the said network to be established characterized in that it comprises at least the following elements:

• At a low-capacity node Ni of the network:
  • A task or processing operations deployment manager (40),
  • A storage module (41) for the said tasks received via a deployment manager for the tasks (40),
  • A processor module (43) for the said tasks, the said module using basic operations (44) present in the said node,
  • An interface with local sensors (45),
  • A service oriented network communications module (47),
  • A global mediation module (46),
    the said various sensor nodes within the said network each executing one or more of the specific deployed tasks,
• At a master node used in the deployment phase:
  • A task deployment manager (56).

Use of the system for data fusion.

Claims

1. System enabling the dynamic deployment and/or the creation of tasks within a network comprising at least one master node (0) and several sensor nodes Ni having limited processing capacities, the network supporting a communications software application exposing the functionalities of each sensor node as services on the said network and a mediation mechanism allowing communications between the services of various sensor nodes of the said network to be established wherein it comprises at least the following elements:

At a low-capacity node Ni of the network;

A task or processing operations deployment manager (40),

A storage module (41) for the said tasks received via a deployment manager for the tasks (40),

A processor module (43) for the said tasks, the said module using basic operations (44) present in the said node,

An interface with local sensors (45),

A service oriented network communications module (47), exposing the functionalities internal to other nodes of the network via input and output interfaces and allowing the said services to be controlled on other nodes,

A global mediation module (46) establishing communications between the tasks of the various nodes, delivering and consuming one or more of the said services via the service oriented communications module (47),

the said various sensor nodes within the said network each executing one or more of the specific deployed tasks,

At a master node used in the deployment phase;

A task deployment manager (56).

2. System according to claim 1, wherein the module for the basic operations (44) of a node Ni of the network comprises at least one operation allowing a task executed on the said node to dynamically create a new service which will be exposed across the said network.

3. System according to claim 1, wherein the said global service mediation module (46) for a node Ni of the network comprises at least one module for uncovering the new services offered by one or more of the other nodes of the network.

4. System for the dynamic creation of services or of distributed processing operations according to claim 1, wherein the system further comprises a tool (71) allowing a description of the behaviour of a distributed processing operation to be globally generated starting from a library of basic functions (70) and a module (72) transforming the said description into a set of individual tasks (73₁), (73₂), (73₃), (73₄), designed to be deployed on each of the sensor nodes Ni.

5. System according to claim 1, wherein at least one node comprises a service gateway (57) designed to ensure interoperability between the tasks being executed on sensor nodes Ni having limited processing capacities and services or tasks being executed on unconstrained nodes or on an information processing system.

6. System according to claim 4, wherein the system for global description of the distributed processing operation (71) and the library of basic functions (70) allow tasks to be defined that are designed for nodes having non-uniform processing capacities, and the associated deployment module (74) allows individual tasks generated (73₁), (73₂), (73₃), (73₄) to be deployed over nodes with non-uniform capacities, communicating via the said service gateway (57).

7. System according to claim 6, wherein the system further comprises a module for supervision and management of the tasks deployed (76), allowing the execution of the tasks deployed over the sensor nodes to be simulated, tested, supervised and reconfigured using the description of the global behaviour of the distributed processing operation (71).

8. System according to claim 1, wherein the communications module (47) is a stack of the WSN-SOA type.

9. System according to claim 5, wherein the system for global description of the distributed processing operation (71) and the library of basic functions (70) allow tasks to be defined that are designed for nodes having non-uniform processing capacities, and the associated deployment module (74) allows individual tasks generated (73₁), (73₂), (73₃), (73₄) to be deployed over nodes with non-uniform capacities, communicating via the said service gateway (57).

10. System according to claim 4, wherein the system further comprises a module for supervision and management of the tasks deployed (76), allowing the execution of the tasks deployed over the sensor nodes to be simulated, tested, supervised and reconfigured using the description of the global behaviour of the distributed processing operation (71).
