Research on Improved Wireless Sensor Node Localization Algorithm

As the wireless sensor network has incomparable advantages than any other network,it has a wide range of applications in many felds.It is the basic work for other applications to localization unknown sensor node of wireless sensor network.This paper analyzes the localization technology in wireless sensor networks and researches on the existing localization algorithm,proposes an improved distributed localization algorithm based on an existing algorithm.The algorithm uses the RSSI measuring distance without adding other hardware.And it improves effciency and reduces power consumption through a distributed algorithm.And it improves localization accuracy through the average of multiple localizations.This localization algorithm reduces the energy consumption of network and extends the network life.
