Abstract: This paper describes the deployment of a wireless sensor network for monitoring humanmotion and position in an indoor environment.An RSSI based localization algorithm is implemented，which uses an in-building radio propagation model and a compensating model to provide accurate indoor location information.The performance of the network protocols and localization algorithm is evaluated using simulated and real experimental data.
