摘要
为研究无线传感器网对能耗的要求,提出一种无线传感器网媒体接入控制协议,对应用场景进行抽象,基于OPNET构建无线传感器网仿真平台,测试不同应用场景下各种媒体接入控制协议的能耗和延时性能,实验结果表明,任何一类媒体接入控制协议均能在不同应用场景中提供较好的性能,但不是最优的。
In order to research the requirements of energy consumption in Wireless Sensor Networks（WSNs）, a Media Access Control（MAC） protocol in WSNs is proposed, which abstracts the different application scenes. Simulation platform of WSNs based on OPNET is set up. The performances of energy consumption and timelag in different application scenes are tested. Experimental results show that all kinds of MAC protocols can provide better performances in each application scene, but all the performances are not best.
