自组织网络中LANMAR协议的仿真研究

Research and Simulation of LANMAR Protocol in Mobile Ad Hoc Networks

LANMAR协议是一种适用于大规模、重负荷自组织网络的路由协议,利用节点的群组移动特性减小路由表的长度和控制开销,可提供灵活的路由框架。详细分析了LANMAR协议的机制和特点,基于一种典型的参考点群组移动模型在QualNet平台下仿真研究了LRMAR协议的性能,分析了移动速度和负荷对LRMAR协议性能的影响,并与AODV协议和FSR协议进行了性能比较。仿真结果表明,LANMAR协议在高速、重负荷条件下端到端延迟、分组传输率和控制开销等方面具有明显的优势。

LANMAR （Landmark Routing Protocol） is a routing protocol that utilizes the group mobility of the nodes and fits for large scale and heavy load Ad hoc networks.It can use different local routing protocols,so it has flexible routing mechanism.This paper first analyzes the protocol,then simulates it in QualNet and compares it with AODV and FSR protocol using average end-to-end packet delay,packet delivery fraction and routing load metrics.Simulation experiments show that LANMAR provides good performance in large,heavy load Ad hoc environments in which group mobility applies.
