| 摘 要： | 针对Ad Hoc网络中泛洪广播机制可能带来的大量资源浪费问题,本文提出了一种新型的泛洪广播机制——密度自适应的泛洪广播策略.该策略根据发送节点的邻节点密度,以最密集节点的一次发送将覆盖较多节点为出发点,选取尽可能少的邻节点作为转发节点,减少了分组在网络中的重复传输,大大改善了网络的性能.仿真结果表明,密度自适应泛洪广播策略的性能明显优于普通的泛洪广播策略.

| Abstract: | In this paper we propose the Degree Adaptive flooding Broadcast (DAB) strategy for Ad Hoc networks to efficiently reduce the broadcast overheads in the network.Based on the degree of the nodes,DAB decides which nodes need to re transmit and which nodes only need to receive.The higher the neighbor node's degree,themore nodes it can cover,so this kind of nodes can be selected to resend the broadcasting messages in the networks.The simulation results show that DAB strategy outperforms the ordinary flooding broadcast method for the Ad Hoc networks. |
