摘要
在移动自组织网络中,由于节点的移动没有固定的模式,很多情况下无法得到稳定的网络拓扑,因此传统的无线多跳网络路由协议很难直接运用于移动自组织网络。本文分析了基于地理位置的路由模型,引入移动节点的当前位置信息和目标位置信息,结合报文的投递目标进行在报文转发中做最优路由选择。基于影响路由选择的三个要素:移动节点目标位置与报文目标位置的距离、移动节点目标位置与报文目标位置的夹角和移动节点本身的移动速度,提出了一种基于位置信息辅助的移动自组织网络路由算法(LIBR)。仿真结果表明,所提算法在转发成功率、转发延时以及转发次数等性能参数方面与现有的路由算法相比,具有更好的性能表现。
In Mobile Ad hoc Networks, since the mobile node does not exist a fixed pattern, it is unable to obtain a stablenetwork topology in many cases. So traditional wireless multi-hop routing protocols are difficult to apply in MANETsdirectly. By analyzing the geographic-based routing model, mobile nodes’ current information and the destinationinformation is introduced to help the optimal routing selection. Based on three main factors of the routing selection, i.e., thedistance between node’s destination and message’s destination, the angle between node’s moving direction and message’sforwarding direction and the moving speed of mobile node, we propose a location information based routing algorithm.Simulation results show that the proposed algorithm outperform the existing routing algorithms in delivery rate and otherperformance parameters.
