摘要
首先简要描述了Anycast路由及其在移动Adhoc网络中应用的重要性。详细讨论了Anycast路由和Unicast路由的网络性能并对分组的平均跳数、分组的平均传输时延和网络平均连通性之间的关系进行了比较。在此基础上提出适用于移动Adhoc网络的AAODV路由协议并对其进行了详细的功能描述,对不同拓扑网络结构的路由优化、分组转发的成功率和路由开销等性能参数进行详细的比较分析。最后在Linux平台上利用NS2软件工具对AAODV路由协议进行了网络仿真。
Anycast-Routing protocol and the significance of its application in mobile Ad hoc networks are briefly described first.Then,the network performances of anycast-routing and unicast-routing are discussed,and the relationships between mean packet hop count,mean message packet delay and average network connectivity are also compared.On this basis,an AAODV routing protocol for mobile Ad hoc networks is presented,and its functions are described in detail.An analysis for the parameters of network performance,such as routing optimality,packet delivery-ratio and overhead of different topologies is made by comparison.Finally,a sound simulation with NS2 built on the platform of linux system system has been done to show the performance of AAODV.
