| 摘 要： | Ad Hoc网络和有线网络的互联是网络发展的必然。为实现有线节点与无线节点间的通信，在采用AODV路由协议的Ad Hoc网络中通过添加网关节点的方式实现AODV协议无线网络的有线接入。在AODV路由协议中添加了网关节点，并结合实际网络场景进行了网关公告的自适应性能优化。对改进后的AODV路由协议在NS2中进行了仿真。仿真结果表明：实现了改进AODV协议无线节点与有线节点的通信，降低了网关引入的网络开销，可以灵活地响应网络拓扑变化。

| Abstract: | It is necessary to connect Ad Hoc with wired network.For the purpose of implementing the communication between wired network nodes and wireless network nodes,gateway nodes are added into the AODV routing protocol in Ad Hoc environment so that wireless nodes can access the wired nodes.Gateway nodes are extended and optimized according to the real network scenery,the optimizations are mainly about the self-adapting of the gateway advertisement.Simulation is made under the NS2 environment to find the adaptive capability of the gateway advertisement sending interval.The result of the simulation shows that the wireless network nodes which use the improved AODV routing protocol can communicate with the wired nodes and the improved AODV protocol reduces the consumption which is caused by the gateway nodes,and it can meet with the network topology alteration rapidly. |
