摘要: Ad Hoc网络是一种多跳的自组织网络,网络是由移动的节点组成。Ad Hoc网络的许多应用都依赖层次结构的支持,簇结构是Ad Hoc网络中应用最为广泛的层次结构,而这种层次结构的形成和维护依赖于某种分簇算法。提出了移动节点的平均连接度计算方法,并在此基础上提出了一种新的分簇算法(MCDA),通过对算法进行分析和仿真测试,证明了该算法的有效性。

Abstract: Ad Hoc network is a kind of multi-hop self-organizing network.The network is dynamic in nature due to the mobility of nodes.Many mobile Ad Hoc applications depend on the hierarchical structure,and clustering is the most popular method with a hierarchical structure in the mobile Ad Hoc networks.A calculation algorithm for node’s mean connectivity degree is proposed.Then a novel clustering algorithm(MCDA) is proposed.Analysis and simulation of the algorithm have been implemented and validity of the algorithm has been proved.

Key words: Ad Hoc network, clustering algorithm, cluster and cluster header, mean connectivity degree
