中文摘要：
针对移动终端作为无线传感器网络中的移动sink情况下，提出了具有多个移动sink的稀疏无线传感器网络体系结构M^2S^2N。考虑到移动终端广泛存在的特性，为了有效地收集传感数据，提出了无线传感器网络中对移动sink的选择策略，并在此基础上提出了一种适合于M^2S^2N的基于功率控制的机会传输调度算法。仿真和分析表明选择最佳的移动sink可以有效地提高传感器节点的能量有效性和数据传输成功率。
英文摘要：
Using mobile devices as sinks for efficient data collection in wireless sensor network （WSN）, the architecture of multiple mobile sinks sparse wireless sensor network （M^2S^2N） was introduced. By taking the ubiquitous nature of mobile devices into consideration, different selection schemes of mobile sinks in M^2S^2N were compared, and an opportunistic transmission scheduling algorithm （OTSA） for M^2S^2N was further proposed. Simulation results indicate that the proposed sink selection scheme in OTSA-M^2S^2N is effective and can significantly improve the performance such as energy efficiency and successful transmission ratio.
