摘要
广播是移动Ad hoc网络提供路由发现、地址解析等网络功能的一项重要操作.为了减少了泛洪广播算法中的端到端延迟,有效利用有限的带宽资源,解决广播风暴问题,文中提出了一种距离感知的广播技术,即基于最优距离的概率广播方案.本方案通过结合概率算法和距离感知来解决广播风暴问题,以高可达率和低延迟在网络中传播广播数据包.仿真结果显示与主流的泛洪算法和概率广播算法相比,本方案在可到达率、端到端延迟及重播概率等方面的性能有所提高.
Broadcasting is an essential operation in Mobile Ad hoc Networks （MANETs） tor provldmg network functions. In this paper, a distance perception technique probalitistic broadcast scheme based on optimized distance is proposed to reduce the end to end delay in flooding, utilize the limited band width rescourees efficiently and counter the problem of the broadcast storm. In this scheme the gossiping scheme was integrated, with a distance perception broadcast scheme, which enabled it to counter the broadcast storm problem to spread the broadcast packets throughout the network with high reachability and reduced latency. The results show that the proposed scheme is superior to the most popular flooding and gossiping schemes in reachability, end to end delay and saved rebroadcast.
