无线自组网竞争类MAC协议分析及研究

摘要

无线自组织网络是一种无基础设施的移动网络,并且每个节点的业务多以突发业务为主,因此信道资源分配适用于采用竞争方式.本文在对无线自组网各种典型竞争类MAC协议进行分析及探讨的基础上,采用Opnet仿真建模环境,刨建出各协议的状态分析模型,并在此基础上对各协议的性能优劣进行了比较总结.论文对无线自组网各协议仿真建模研究及选择高效适用的MAC技术方案具有实际参考价值.%Wireless self-organizing networks is a kind of mobile network without infrastructure. The traffic of every node is mostly burst traffic. For this reason, channel resources allocation is suitable for adopting competion method. This article constructed analyzing models of the status of every protocol by using Opnet simulating and modeling environment base on study and analysis of typical competing type wireless self-organizing networks. Also, it compares and summarizes the advantages and disadvantages of each protocol's performance. This article has practical and significant value for study of simulating and modeling of each protocol of wireless self-organizing networks and selecting suitable and efficient MAC.
