引入移动sinks节点是解决网络连通性、能耗平衡、提高网络生命周期和网络容量的有效方法。针对移动sinks节点的移动机制直接与网络性能相关,结合mWSNs体系结构,分析了基于随机移动模型的网络性能,提出了零数据包分片率的随机移动模型。理论分析与仿真结果表明,该模型能够保证数据零分片,提高了网络的时延性能和数据包传输成功率。

Introducing WSNs is an effective method to solve the problems, such as network connection, energy balance, network lifetime and capacity. The mobility mechanism of mobile sinks can directly affect the network performance. Firstly, studied the architecture of mWSNs. And then,analyzed the network performance based on stochastic mobile model. Thirdly,proposed a new random mobile model that could provide zero data packet split rate. Theoretical analysis and simulation results show that the new model can improve the network performance such as delay and zero data packet split rate.
