| 摘 要： | 在移动Ad Hoc网络中,随着网络节点移动速度加快,MAC层拥塞程度加剧,势必严重影响网络数据传输成功率和加大传输延时。本文通过对HELLO消息、TC消息的修改来获取并传输MAC层的拥塞信息同时通过仿真实验设定阀值,对OL-SR(Optimized Link State Routing)路由协议进行MPR重定义以实现数据的及时传输。仿真实验表明改进后的方案在节点移动速度较快时,能够显著提高数据传输成功率,增加网络承受负载能力,提高OLSR的路由传输能力。

| Abstract: | The high-speed nodes will aggravate congestion of MAC,influence the rate of success for data and increase the time-lag of transmission in Ad Hoc.The solution reduces discarded packets in the physical and MAC layers modifying HELLO and TC(topolo-gy control)messages to carry congestion information of the MAC layer for the congestion evaluation and bettering the MPR selection algorithm to choose a route which transmit data is timely.Simulation results in the wide range of different moving speed of the mobile n... |
