Wireless Sensor Networks (WSNs) have become a hot research topic in academia as well as in industry in recent years due to its wide range of applications ranging from medical research to military. In this paper, we study the effect of mobile sink in WSN performance. The WSNs should allow a systematic deployment of sensor nodes including mobility among the sensor nodes. 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 as evaluation parameter goodput and depletion to evaluate the performance of WSNs considering different speeds of mobile sink. The simulation results show that, when the \( T_{r} \) is lower than 10 pps, the network is not congested and the goodput is higher when the sink node moves faster (20 m/s). When \( T_{r} \) is lower than 10, the depletion is higher when sink moves with lower speed (5 m/s). But, when \( T_{r} \) is larger than 10, the depletion is higher for higher values of the sink speed (20 m/s).
