一种蜂窝辅助的AODV路由协议

A Cellular Aided AODV Routing Protocol

首先提出了一种新的融合Ad Hoc和蜂窝网络体系结构。接着在这种融合网络结构下,对传统AODV路由协议进行了改进,设计了一种蜂窝辅助的AODV路由协议(CA-AODV)。CA-AODV路由协议利用蜂窝系统中代理节点所保存的移动ad hoc节点位置信息,来维护、更新节点中的路由,这种主动维护路由信息的方法从而可以提高传统AODV协议的性能。最后文中通过NS-2仿真表明:在数据发送率较高的情况下,CA-AODV路由协议能显著提高传统AODV协议的系统参数性能。

This paper firstly proposes a novel integrated Ad Hoc and cellular network architecture. Then,with this architecture, we design a cellular aided AODV routing protocol （CA-AODV）. Based on the AODV routing protocol, CA-AODV makes use of the location information in the agent node of cellular systems to maintain and updating the routes of mobile ad hoc stations. This proactively routing maintenance can improve the performance of AODV routing protocol. Finally an extensive simulation in NS-2 shows that when the packets delivering rate is high, the CA-AODV can improve the system performance of the traditional AODV significantly.
