In this paper a novel system to monitor warehouse with wireless sensor networks is proposed. The system consists of wireless nodes and monitor. Wireless sensor nodes collect temperature and humidity information and send to monitor. Monitor provides GUI for warehouse operators. The design of wireless nodes and monitor are introduced in detail.
In this paper a novel method for tracking moving objects in wireless sensor network is presented. Firstly, the observed position is estimated by a moving object localization algorithm based on Received Signal Strength Indication (RSSI). Then, the estimated position is filtered by a Kalman filter in order to obtain a smoothed trajectory of moving objects movement. Simulation results show the effectiveness...
