摘要
Ad Hoc网络中各个节点能量有限,因此设计一个高效的路由协议在Ad Hoc网络显得十分重要。本文在分析了传统的AODV路由协议及目前已经提出的能量感知类路由协议的基础上,从节点的剩余能量和节点的通信状态出发,提出了节点综合稳定度的计算公式,并以此对AODV路由协议进行了改善。仿真结果表明,该方法是有效的,它延长了网络的生存时间,提高了网络的传包率。
The energy of each node in ad hoc networks is limited, so it is very important to design an efficient routing protocol in ad hoc networks. The traditional AODV routing protocol and the present energy-aware routing protocol are analyzed in this paper. Based on this, the calculative formula of the comprehensive stability degree of nodes is brought up from the remained energy and communicative state of nodes, which improves the AODV routing protocol. The simulation results show that the approach is effective. It not only prolongs the life time, but also increases the package-delivery rate.
