Abstract: A distributed and cooperative localization method for the target in wireless sensor network system is presented. This new approach uses energy measurements from the individual sensors in the sensor field to detect the targets. The position of the target can be estimated based on a distributed and cooperative localization model using the energy measurements. Extensive simulation results show that this new approach can locate the target effectively. It can reduce the complexity of the processing. It is a feasible and attractive localization method for the wireless sensor network system.

Key words: sensor network, radio localization, distributed processing
