Impact of Mobile Sink for Wireless Sensor Networks Considering Different Radio Models

Wireless Sensor Networks (WSN) 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. The sensors themselves can range from small passive micro sensors to larger scale, controllable weather-sensing platforms. In this work, we investigate how the sensor network performs in the case when the sink node moves using different radio models. We consider good put and depletion metrics to evaluate the performance of WSN. We compare the simulation results when the sink node is mobile and stationary considering lattice topology and AODV protocol. The simulation results have shown that in case of mobile sink, the good put of TwoRayGround radio model is better than Shadowing. However, the consumed energy of Shadowing model is better than TwoRayGround model.
