MANET分簇节点组通信功能的设计与实现

Design and Implementation of Group Communication Function for Clustering Nodes in MANET

提出一种将源路由(DSR)协议与自适应按需加权(AOW)分簇算法相结合的Ad hoc网络体系结构设计方案。利用AOW算法进行分簇,将簇半径严格控制在1跳以内,簇内成员无需路由功能,大大减少了网络路由信息的冗余。簇头运行DSR协议充当路由转发器,使不同簇节点之间的通信依赖于各簇的簇头。模拟结果显示该方案具有良好的性能,并已在Windows XP中实现。

This paper proposes a scheme ofAd hoc network architecture which combines Dynamic Source Routing （DSR） protocol and Adaptive On-demand Weighted（AOW） clustering algorithm. Using AOW algorithm, the cluster radius is strictly controlled within a hop and cluster-members do not need routing function, greatly reducing the redundancy of routing information. Each cluster-header implements the DSR Protocol, working as a router. The communication between nodes coming from different clusters relies on cluster-headers. Simulation result shows that the scheme has good performance. It has been implemented in Windows XP operating system.
