Distributed Cooperative Localization for Mobile Wireless Sensor Networks

Abstract

In this letter, we consider a mobile wireless sensor network (WSN), in which all nodes have some knowledge about their movements. Exploiting the sensor mobility information in the localization process, we develop novel cooperative second-order cone programming-based localization algorithms for both time-of-arrival and received signal strength measurement models. We show that the developed algorithms can also be implemented in a distributed manner, and hence, are suitable for large-scale WSNs. The proposed mobility-aided localization framework significantly improves the localization accuracy and addresses some typical positioning problems.
