Abstract
A method for locating sensors situated in a geographical area including of at least one reference sub-area. the sensors include: at least one first sensor, each first sensor being associated with a reference sub-area in which it is situated; and at least one second sensor, each second sensor not being associated with any sub-area. The method includes: grouping the sensors into a plurality of groups based on data from the sensors; for at least one group of sensors, determining whether the group includes a first sensor; an if the group includes a first sensor, associating each second sensor of the group with the sub-area corresponding to the first sensor.
Claims10
A method, implemented by a device comprising at least one hardware component, for locating sensors situated in a geographical area, said geographical area comprising at least one reference sub-area, said sensors comprising:
- at least one located sensor defined as being situated in a respective reference sub-area and as having an identifier associated, in a lookup table stored in a memory, with said respective reference sub-area;
- and
- at least one unlocated sensor defined as having an identifier for which a location is not known in the lookup table;
- the method comprising:
- receiving data from the sensors located in the geographic area, and:
- a) grouping said sensors into a plurality of groups of spatially close sensors by partitioning the data received from said sensors based on spatial correlations established on the basis of said data from said sensors;
- b) for at least one group of sensors among the plurality of groups, determining whether or not the group comprises a located sensor of the at least one located sensor by checking in the lookup table;
- and
- c) when the device determines that the group comprises a located sensor of the at least one located sensor, associating each of the at least one unlocated sensor of the group with the reference sub-area with which the located sensor of the group is associated, by updating the lookup table, and
- when the device determines that the group comprises only unlocated sensors, issuing a signal to request information relating to a reference sub-area of the at least one reference sub-area in which each unlocated sensor of the group is situated.
A device for locating sensors situated in a geographical area, said geographical area comprising at least one reference sub-area, said sensors comprising:
- at least one located sensor defined as being situated in a respective reference sub-area and as having an identifier associated, in a lookup table stored in a memory, with said respective reference sub-area;
- and
- at least one unlocated sensor defined as having an identifier for which a location is not known in the lookup table;
- the device comprising a circuit configured to receive data from the sensors located in the geographic area, and:
- a) group said sensors into a plurality of groups of spatially close sensors by partitioning the data received from said sensors based on spatial correlations established on the basis of said data from said sensors;
- b) for at least one group of sensors among the plurality of groups, determine whether or not the group comprises a located sensor of the at least one located sensor by checking in the lookup table;
- and
- c) when the circuit determines that the group comprises a located sensor of the at least one located sensor, associate each of the at least one unlocated sensor of the group with the reference sub-area with which the located sensor of the group is associated, by updating the lookup table, and
- when the circuit determines that the group comprises only unlocated sensors, issue a signal to request information relating to a reference sub-area of the at least one reference sub-area in which each unlocated sensor of the group is situated.

- at least one located sensor defined as being situated in a respective reference sub-area and as having an identifier associated, in a lookup table stored in a memory, with said respective reference sub-area;
- and
- at least one unlocated sensor defined as having an identifier for which a location is not known in the lookup table;
- wherein the instructions configure the device to receive data from the sensors located in the geographic area, and:
- a) group said sensors into a plurality of groups of spatially close sensors by partitioning data from said sensors based on spatial correlations established on the basis of said data from said sensors;
- b) for at least one group of sensors among the plurality of groups, determine whether or not the group comprises a located sensor of the at least one located sensor by checking in the lookup table;
- and
- c) when the device determines that the group comprises a located sensor of the at least one located sensor, associate each of the at least one unlocated sensor of the group with the reference sub-area with which the located sensor of the group is associated, by updating the lookup table, and
- when the device determines that the group comprises only unlocated sensors, issue a signal to request information relating to a reference sub-area of the at least one reference sub-area in which each unlocated sensor of the group is situated.
