摘要
随着电子和通信等技术的发展,无人机趋于小型化和集群化,在民用领域的用途越来越广泛。为了在日益复杂的任务与应用环境中实现自主控制,无人机自组网成为提供高效灵活机间通信的关键,而无人机自组网中的路由协议一直是核心研究问题之一。文章使用NS-2网络协议仿真软件,在理想场景中对移动自组网的两种主流路由协议AODV和OLSR进行性能测试分析,选用AODV作为无人机自组网的路由协议。随后,针对无人机网络节点移动速度快和网络拓扑变化频繁的特点,对现有AODV协议的路由选择方法进行了优化,以定义的路由代价代替跳数作为选路判据,有效提高了分组投递率和路由控制开销等性能。
With the development of electronic and communication technologies,UAVs tend to be miniaturized and swarmed.It can be implemented in many civilian fields.In order to realize the autonomous control in increasingly complex tasks and application environment,the FANETs which can provide efficient and flexible communication among the UAVs becomes critical.And the routing protocols have always been the core research issues.This article reviews the performance evaluation of AODV and OLSR routing protocols in ideal application using NS-2 software package,choosing AODV routing protocol for FANETs.Then,optimization of the existing AODV routing protocol is proposed based on the defined routing cost instead of the hop count.Simulations show it has better network performance.
