Abstract: Energy efficiency is a pivotal problem of Wireless Sensor Network(WSN). WSN can efficient prolong the lifetime of WSN via mobile sinks. Some fundamental design parameters in Mobile Wireless Sensor Network(MWSN) are investigated in this paper, such as cluster size, mobile sink velocity, mobile sink number, packet lifecycle and the impact of them on energy efficient. It proposes the optimization cluster hops scheme through careful analysis single hop scheme and multi hops scheme, and the extensive simulations is designed to evaluate the performance of mobile sinks WSN in terms of energy consumption.

Key words: Wireless Sensor Network(WSN), mobility, cluster, energy efficiency
