Abstract: Event detection is a major issue for applications of wireless sensor networks. In order to detect an event, a sensor network has to identify which application-specific incident has occurred based on the raw data gathered by individual sensor nodes. Sensor networks are a sensing, computing and communication infrastructure that are able to observe and respond to phenomena in the natural environment and in our physical and cyber infrastructure. In this paper, we propose a sensor network with mobile and static sensor nodes. We investigate how the sensor network performs in the case when the sensor nodes move. We compare the simulation results for two cases: the sensor network with stationary sensor nodes and multi mobile sensor nodes. The simulation results have shown that for the multi mobile sensors, the goodput is unstable. Also, the goodput of stationary sensors is better than multi mobile sensors. In case of consumed energy, the consumed energy of multi mobile sensors is better than stationary sensors. Also, the RE of multi mobile sensors is better than stationary sensors.
