An Assisting and Cooperative Localization Method in Wireless Sensor Networks
Wireless sensor networks (WSNs) are important for a number of strategic applications. Target localization is an important task in WSNs. In this paper, an assisting and cooperative localization method for the target in wireless sensor network systems is presented. This new approach uses energy measurements from the individual sensors in the sensor field to detect the targets first. Then the position of the target can be estimated using a distributed and cooperative localization model based on a simple geometry relation between the sensor nodes and the target. Extensive simulation results show that the new approach can locate the target effectively. Besides, it can reduce the complexity of the processing. Therefore, it is a feasible and attractive localization method for the wireless sensor network system.
