Messenger Nodes Based Routing Protocol for Sparse MANET and Performance Analysis
首发时间:2009-03-20
Abstract:Recently, the routing issue in sparse Mobile Ad hoc NETwork (MANET) has drawn many researchers’ attention. However, almost all routing protocols resort to either Global Position System (GPS) or trajectory-control, which increase the cost of entire network. In this paper, the Messenger nodes based Routing (MR) protocol, a novel opportunistic routing protocol, is proposed to serve sparse MANET without either GPS or trajectory-control. With the assistance of the MR protocol, sparse MANET can accordingly be deployed much more conveniently. The simulation results in this paper demonstrate that the MR protocol is able to provide a high rate of packets reception. Moreover, the theoretical models for both the average delivery delay and the average number of hops of the MR protocol are constructed in this paper. Finally, the comparison between simulation and theoretical analysis indicates the coincidence of the analytical models with the simulation results.

稀疏MANET中基于信使节点的路由协议及性能分析
摘要:稀疏移动自组织网络(Mobile Ad hoc NETwork, MANET)中的路由问题近来受到很多研究者的关注。遗憾的是,几乎所有的路由协议均诉诸于全球定位系统(Global Position System, GPS)或轨迹控制,导致整个网络的开销增大。本文针对稀疏MANET提出了所谓的基于信使节点的路由(Messenger nodes based Routing, MR)协议,它是一种新颖的机会型路由协议,既不需要GPS也不需要轨迹控制。借助于MR协议,稀疏MANET可以更方便地进行部署。本文仿真结果表明,MR协议能够提供较高的包接收率。进一步地,本文构建了MR协议的平均分发时延和平均路由跳数的理论模型。仿真结果与理论分析之间的比较表明,本文构建的分析模型与仿真结果相一致。
