摘要: 为了提高网络的综合性能,充分考虑了数据链路层和网络层的影响因素。对比分析了不同Ma。接入协议的切换方法,为无线自组网络选择了一个合适的路由和接入协议。通过在NS-2中仿真Mac层的802. lla和802. 11Ext路由场景,对AODV协议的归一化路由开销、路由发现频率、端到端平均时延以及数据分组投递率进行了全面的分析比较。结果表明,802. 11Ext接入协议具有明显的优势特点,更加稳定、更适合移动网络。

Abstract: In order to improve the comprehensive performance of network, this paper fully consided the influence factor at the data link layer and network layer, compared and analysed of switching methods in the different Mac access protocol, selected an appropriate routing and access protocol for Ad Hoc. Simulating the scene based on Mac layer of 802. lla and 802. 11Ext routing in NS-2,the paper fully analyzed and summarized AODV protocol performance about normalized routing load and route discovery frequency and end-to-end average delay and packet delivery ratio. The results show that 802. 11Ext has many obvious advantages, it is more stable and suitable for mobile network.
