Wireless sensor networks (WSNs) have been proposed for a multitude of location-dependent applications. To stamp the collected data and facilitate communication protocols, it is necessary to identify the location of each sensor. In this paper, we discuss the performance of two novel positioning schemes, which use two generalized geometrical localization algorithms to achieve an accurate estimation based on time-ofarrival (TOA) measurements without time synchronization. In order to improve the… CONTINUE READING
