摘要
结合mWSNs体系结构,分析了移动sinks无线传感器网络的时延组成和时延特性,并通过仿真实验分析了移动性对时延的影响。该分析结果既能用于mWSNs时延系统性能评价,又可为mWSNs系统参数(如移动sinks数量、速度、传输半径及数据包长度等)优化提供理论依据。同时,时延性能要与能量消耗综合考虑。
Firstly,analyzed the delay composition and delay characteristic based on the architecture of mWSNs, then,investigated the influence of sink mobility on delay through some simulation experiments. The result is not only benefits for the analysis of delay and the evaluation of system performance but also provides the theoretical evidence of the optimizing of system parameters, such as mobile sinks＇ s number, mobile sinks velocity , transmission radius and the length of data. And the delays of WSN should be studied with energy efficiency.
