【摘要】 自组网是一种由移动节点自组织形成的、不需要任何基础设施的网络,针对其随机的拓扑结构研究人员提出了基于分簇结构的拓扑机制,用于网络路由优化和安全控制。然而,这些算法在不同的移动环境中面临着不同的挑战,因而所表现出来的性能也各不相同,为进一步验证这些算法在不同移动环境中的有效性,文中使用Delphi设计了自组网的几个典型分簇算法,通过随机环境的仿真实验,得到相关仿真数据,分析比较了这些算法的性能,为进一步的研究提供依据。更多还原

【Abstract】 Ad Hoc network is a self-organized network,consistingof mobile nodes without any infrastructure.Cluster-based topology control strategies have been proposed to meet to routing optimization and security control due to the random environment of Ad Hoc network.But these algorithms vary in performance when facing different mobile environment.Some proposed cluster algorithms were designed by using the tool of Delphi to test them.The data were analyzed in a random simulation environment and the algorithm’s performances were compared in this paper,from which the future study can benefit.更多还原
