Research on wireless sensor network node localization algorithm

Wireless sensor network(WSN) are wireless self-organizing network that can monitor, perceive and gather various messages from monitoring object, then process and send them to user. For the localization algorithm of wireless sensor network exists a big positioning error in wireless communication. Wireless sensor network communication system is built up. According to the anchor nodes and unknown nodes, location algorithm of WSN is proposed. The performance of the node density and location error are simulated and analyzed. The simulation results shows that the performance of proposed WSN location error is better than the traditional algorithms.
