Performance Evaluation of Wireless Sensor Networks for Mobile Sensor Nodes Considering Goodput and Depletion Metrics

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 set-up for performing tasks like sensing a phenomenon or monitoring a region. 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 good put is unstable. The good put of stationary sensors is better than multi mobile sensors, but the consumed energy of multi mobile sensors is better than stationary sensors.
