In this paper, we study the effect of mobile sink and mobile sensors in WSN performance. The WSNs should allow a systematic deployment of sensor nodes including mobility among them. The disseminated data from the sensor nodes are gathered at the sink node. Data dissemination is the major source for energy consumption in WSNs. We consider goodput, depletion and Routing Efficiency (RE) parameters to evaluate the performance of WSNs considering different speeds of mobile sink and sensor nodes. The simulation results show that when the network is congested (Tr is higher), the goodput decreases. For Static Sink (SS) scenario, the difference between evaluation parameters is not too much. For Moving Sink (MS) scenario, the goodput is higher for 10m/s and RE is higher when moving speed is 5m/s.
