TDOA-Based Joint Synchronization and Localization Algorithm for Asynchronous Wireless Sensor Networks

This paper presents a joint synchronization and localization algorithm based on the time-difference-of-arrival (TDOA) for asynchronous Wireless Sensor Networks (WSNs), where the positions of anchors are relatively fixed but unknown. To obtain time synchronization and anchor positions, each anchor br...
