Energy efficiency is one of important issues in Wireless Sensor Networks (WSNs). In the WSN energy, memory and processor of the nodes are limit. The nodes send their data to the sink by passing to nodes near the sink for further processing. Sensors near the sinks called hotspot. The hotspots relay other sensors' data and will lose their energy quickly. To avoid energy holes, Sink mobility is used to balance load on network. To determine appropriate sink site, different methods are developed. In this paper we propose a method to find optimal sink location based on convex hull. Simulation results show this proposed improves lifetime.
