分层Ad Hoc网络中同步领导者选举算法的研究

近年来,Ad Hoc网络以其方便、快捷、不受网络基础设施制约等特点得到了广泛的研究和应用。然而,在分层Ad Hoc网络进行视频信息传输的过程中,由于节点移动及网络状况等原因有可能出现簇头节点缺失的情况,影响网络的正常通信。针对分层Ad Hoc网络中高层节点移动性差这一特点设计并实现了基于分层Ad Hoc网络高层网络同步领导者选举算法,解决了上述问题。系统还引入了副主席机制,并通过实验证明,当网络中存在着上一轮选举后产生的副主席节点时,选举时间将显著缩短。算法也可应用于小型临时视频会议系统中以解决视频会议中主持人缺失及更替的问题。

Research of Synchronous Leader Election Algorithm on Hierarchy Ad Hoc Network

In recent years,ad hoc network is widely studied and used because of its convenient,rapid and infrastructure-free characteristics.However,due to the node mobility and network performance,cluster leader node may be lost,which will affect the communication severely.This paper mainly researched on the architecture of hierarchy ad hoc network and designed high-level synchronous algorithm according to the features of poor mobility of high-level node.Based on that,the leader election system in hierarchy ad hoc ne...
