Grid division-based probabilistic localization algorithm for WSN
无线传感器网络中一种基于栅格划分的概率定位算法

The Received Signal Strength Indicator(RSSI)-based nodes localization algorithms are extensively applied in wireless sensor networks.Due to the influence of wireless signal attenuation and the channel barrier shielding,the localization accuracy of these algorithms are not high.A grid division-based probabilistic localization algorithm was put forward.This new algorithm first divided the area where the unknown nodes may exist into a number of grids.Then,it calculated out the confidence of every grid under th...
