信道接入协议FAMAC的仿真实现与性能分析

The Simulation Implementation and Analysis of the Performance of Channel Access Protocol FAMAC

Ad hoc网络是一种特殊的无中心无线网络,信道接入协议对网络性能起着决定性的作用。本文首先介绍了一种基于多信道的Ad hoc网络信道接入协议FAMAC,然后给出了在GloMoSim中实现FAMAC仿真的方法,并对难点问题的解决方案做了详细介绍。文章的最后给出了2种拓扑结构下协议性能的仿真结果。

Ad hoc network is a special centerless wireless network and the channel access protocol has crucial impact on the network performance. At first, a multi-channel based channel access protocolFAMAC is introduced in this paper, then the way of simulating FAMAC in the GloMoSim is proposed and the solution of difficult problem is discussed in detail. In the end, we present the simulation result of the protocol performance in two different topologies.
