摘要：

在AODV(Ad Hoc on-demand distance vector routing)协议的基础上通过添加捎带机制,并增加了由当前时刻和几段历史时期邻居稳定性的加权值来最终决定的节点稳定性,提出了一种能够有效减小控制开销和端到端时延的改进协议Improved NCRAODV (improved neighbor change ratio AODV)。NS2仿真结果表明,Improved NCR-AODV可以在很大程度上提高网络性能。

Abstract:

An improved NCR-AODV (improved neighbor change ratio AODV) that can greatly reduce route cost and end-to-end delay is presented. A piggyback mechanism is added into the AODV protocol. Then the weighted neighbor change ratio is introduced which means jointly considering NCRs both at the current time and historical times. The results of NS2 simulation show that the proposed Improved NCR-AODV can greatly enhance the network performance.

Key words: Ad Hoc networks; AODV; piggyback; weighted neighbor stability; NS2 simulation
