摘要
自组性分级结构可以优化无线自组网的性能与可扩展性。以DSR动态源路由与AODV按需平面距离矢量路由协议,对所提出的分级结构的性能进行评估,并与常规的平面式结构进行了比较。结果表明:在DSR与AODV协议中,分级结构明显增大了网络的容量。研究结果显示:无线自组网的容量与网络中节点数目的增加成正比。
Self-organizing hierarchical architecture can improve the performance and scalability properties of Ad hoc wireless networks. The performance of the proposed hierarchical network is evaluated for two well-known classes of Ad hoc routing protocols： dynamic source routing （DSR） and Ad hoc on-demand distance vector （AODV）, and compared with that of a conventional ＂flat＂ Ad hoc network. The results show that the capacity increases with the hierarchical architecture for both DSR and AODV cases. The research result shows that the capacity of the three-tier hierarchical network scales well when the number of forwarding nodes and access points are increased in the right proportions.
