Abstract

A method for managing a wireless sensor network comprising a plurality of sensor nodes, in which the sensor nodes are configured for detecting physical quantities. The method includes setting at least one configuration parameter identifying a service density or monitoring resolution and detecting for a sensor node which physical quantities are detected via respective surrounding sensor nodes. It is verified for the sensor node whether the sensor node is configured for detecting a physical quantity that is also detected via one of the surrounding sensor nodes. It is determined according to the configuration parameter identifying a service density or monitoring resolution, whether the sensor node must activate or de-activate detection of the physical quantity that is also detected via surrounding sensor nodes.

Claims

1. A method for managing a wireless sensor network comprising a plurality of sensor nodes, where said sensor nodes are configured for detecting physical quantities, wherein the method comprises the steps of:

setting at least one configuration parameter identifying a service density or monitoring resolution;

detecting for at least one sensor node of the plurality of sensor nodes which physical quantities are detected via respective surrounding sensor nodes of the plurality of sensor nodes of said sensor network;

verifying for said at least one sensor node whether said at least one sensor node is configured for detecting a physical quantity that is also detected via one of said respective surrounding sensor nodes; and

determining, according to said configuration parameter identifying a service density or monitoring resolution, whether said at least one sensor node must activate or de-activate detection of said physical quantity that is also detected via said respective surrounding sensor nodes.

2. The method according to claim 1, wherein said detection for at least one sensor node of which physical quantities are detected via said respective surrounding sensor nodes of said sensor network comprises the steps of:

sending to said surrounding sensor nodes a request; and

receiving from said surrounding sensor nodes information that enables identification of which physical quantities are detected via said respective surrounding sensor nodes.

3. The method according to claim 2, comprising the steps of:

determining for said at least one sensor node the identifications of the respective surrounding sensor nodes; and

sending to each surrounding sensor node of said surrounding sensor nodes a respective request.

4. The method according to claim 1, wherein each sensor node of the plurality of sensor nodes discloses at pre-set instants information that enables identification of which physical quantities are detected via the sensor node.

5. The method according to claim 1, comprising the step of:

setting for a plurality of physical quantities that can be detected via said sensor network respective configuration parameters identifying respective service densities or respective monitoring resolutions.

10. A computer program product that can be loaded into the memory of at least one computer and comprises portions of software code for implementing the method according to claim 1.

14. A computer program product that can be loaded into the memory of at least one computer and comprises portions of software code for implementing the method according claim 2.

15. A computer program product that can be loaded into the memory of at least one computer and comprises portions of software code for implementing the method according claim 3.
