| 摘 要： | 移动自组织网络(MANET)是一种无需基础设施支持的新型无线网络,其具有很大的动态性.分簇作为一种提高网络可扩展性的方法,在移动自组织网络中有着广泛的应用.在分簇策略3hBAC的基础上,引入了簇头备份机制,提出了一种稳定的MANET分簇策略BH-3hBAC.模拟实验表明,新策略在不影响网络性能的情况下,提高了簇覆盖率、簇的生存时间、平均成员时间,提升了分簇的稳定性,进一步优化了网络的整体性能

| Abstract: | Mobile Ad Hoc Networks (MANET) is a kind of novel wireless network, which does not need basic infrastructure support. As a method that can improve the scalability of the MANET, Clustering has been widely used in MANET. A stable clustering scheme BH-3hBAC is proposed, which introduced the backup of the cluster headers in traditional clustering scheme 3hBAC. Simulation results show that the Average Coverage Rate, the Average Life Time of Clusters and the Membership Time of Clusters are increased dramatically. The stability of clustering and the network performance has been improved prominently with the new scheme. |
