Abstract

In order to reduce the effect on node positioning accuracy due to received signal strength (RSSI) fluctuation in wireless sensor network (WSN), a grid localization algorithm based on RSSI probability distribution is proposed. From analyzing the wireless propagation channel model, it divides the location area into grids. Through comparing the value of RSSI probability likelihood function in grid, the location of the unknown node is obtained. The simulation result shows that this algorithm could effectively improve the performance of positioning accuracy and have better stability.
