Ad Hoc的DSR协议在物联网中的运用

摘要

The networking structure and communication features of Ad Hoc network, which are similar to those of Internet of Things (IOT) are analyzed in this paper. Ad Hoc network can be used in the environment of IOT. The applicability of DSR routing protocol in Ad Hoc network in IOT communication process. NS2 simulation software was used to simulate the communication process of DSR routing protocol in IOT. It can be conclude by the simulation results that the routing protocol DSR according to demand can maintain a higher average packet delivery ratio, lower routing overhead and better QOS when the moving speed of the network nodes is faster or network size grows up. DSR routing protocol in Ad Hoc network is suitable for large-scale and fast-moving IOT with rapid changing topology structure.%分析了移动自组织Ad Hoc网络与物联网相似的组网结构和通信特点，在此基础上讨论了Ad Hoc中DSR路由协议在物联网通信过程中的适用性。并通过NS模拟了DSR路由协议在物联网中的通信过程，由仿真结果可知：当网络节点移动速度增快或网络规模扩大时，采用按需路由协议DSR可以保持较高的分组平均递交率和较低的路由开销，同时网络也具有较好的服务质量，适合规模较大、快速移动、拓扑结构变化较快的物联网。
