Cooperative localization for wireless networks
First Claim
1. A method for a wireless device to self identify a location in a wireless network comprising:
- calculating at least one converted belief representing a distribution of at least one possible location of the wireless device within the wireless network, the at least one converted belief being a function of an arbitrary signal metric associated with a wireless signal received by the wireless device from at least one other wireless device;
determining a self-belief as a function of the at least once converted belief; and
identifying a self location, as a function of the self-belief, within the wireless network.

Abstract
A system and corresponding method using a cooperative localization technique for self identifying a location of a wireless device in a wireless network is presented. The system may estimate an arbitrary signal metric as a function of a signal received by the wireless device from the at least one other wireless device in the wireless network. The system may also convert at least one belief representing a distribution of at least one possible location of the at least one other wireless device to generate at least one converted belief. The system may further determine a self-belief as a function of the at least one converted belief and identify a self location, as a function of the self-belief, within the wireless network.

23. A computer program product having a computer program stored thereon, the computer program defined by instructions which, when executed by a processor in a wireless device in a wireless network, cause the processor to:
-
calculate at least one converted belief representing a distribution of at least one possible location of the wireless device within the wireless network, the at least one converted belief being a function of an arbitrary signal metric associated with a wireless signal received by the wireless device from at least one other wireless device; determine a self-belief as a function of the at least once converted belief; and identify a self location, as a function of the self-belief, within the wireless network.
