Abstract

An indoor localization algorithm based on wireless sensor networks is brought up to fulfill the requirement of accuracy.It is the premises of all to obtain environmental parameters with least square method and choose appropriate leakage model.A brand new method is designed for indoor environment

which is filtering the reliable nodes and dealing with the received signal strength indicator（RSSI）with Gauss model.The accuracy will be further improved after optimization.Experiment data show that this algorithm boasted itself with high accuracy and simple hardware requirements

compared with the result of improved Euclidean algorithm.It is practical to utilize indoors.
