TDOA-Based Joint Synchronization and Localization Algorithm for Asynchronous Wireless Sensor Networks.
IEEE Transactions on Communications(2020)
摘要
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 broadcasts signals periodically, while other anchors receive the broadcasting signals and stamp times-...
