A RSSI Based Localization Algorithm for WSN Using a Mobile Anchor Node

Wireless sensor networks are attracting a great deal of research interest. One of the most interesting researches in these networks is localization of sensor nodes whose accurate is a strong requirement in many applications. In recent years, several techniques have been proposed for localization in wireless sensor networks. In this paper, we present a localization scheme using only one mobile anchor station with receiving signal strength indicator technique, which reduces average localization errors and execution time. The satisfactory simulation results and also comparison of localization errors and execution time between our scheme and similar previous schemes depicts the efficiency of proposed method against previous schemes.
