| 摘 要： | ODMRP协议是无线自组网环境下的一种按需式组播路由协议。论文提出了一种基于链路状态预测的ODMRP协议改进,即LSF-ODMRP路由协议。该协议继承了ODMRP协议的按需式路由发现和更新,并采用了链路状态预测机制LSF(Link Status Forecasting),大大减少了路由失效数并缩短了分组投递延迟,提高了网络性能。通过对LSF-ODMRP协议的模拟仿真实验比较,验证了协议的改进效果。

| Abstract: | ODMRP protocol is an on-demand multicast routing protocol in Ad hoc network.This paper presents the on-demand Multicast Routing Protocol with Link Status Forecasting(LSF-ODMRP).LSF-ODMRP introduces link status forecasting technique to reduce the routing failure number and packet delivery delay,and improves the performance of networks with a small increase of protocol overhead.At the same time,LSF-ODMRP reserves the key merits of ODMRP such as high throughput and energy efficiency in conditions with frequently changing topology.We evaluate LSF-ODMRP performance with ODMRP for Ad hoc networks via extensive and detailed simulation. |
