| 摘 要： | 研究了定向扩散（Directed Diffusion）路由协议的工作原理和传播机制,并使用NS2对其进行了仿真分析.采用平均消耗能量、平均网络延迟和平均分组接收率这三个参数作为性能评价的技术指标,在分别改变网络节点数目、源节点数目、汇聚节点数目的情况下,对定向扩散协议进行了一系列的模拟实验.实验结果显示,定向扩散虽然表现出了较好的性能,但仍然有待提高.

| Abstract: | This paper studies the working principle and propagation mechanism of the directed diffusion（DD） and simulates it by using NS2.Three metrics are chosen to analyze the performance of DD：the average dissipated energy,the average delay and the average delivery ratio.To carry out a series of simulation experiments,the author changes the parameters respectively：the number of network nodes,the number of source nodes and the number of sink nodes.The results show that DD is still to be improved,though it gives a good performance. |
