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

摘要： 能量效率是无线传感器网络的关键性问题，无线传感器网络通过移动sinks节点延长了网络的生命周期。讨论一些关键性要素对能量效率的影响，如簇的大小、移动sinks的速度、数量和数据包生命周期等。分析基于能量效率的单跳、多跳路由模式，提出最优跳数的簇路由模式，并以仿真实验验证移动sinks无线传感器网络的系统性能。
