在AODV协议的基础上设计和实现了一种地理位置信息辅助的AODV协议，LAODV。利用地理位置信息设置RREQ控制分组的广播区域从而减小协议的控制开销。节点的位置信息通过RREQ和RREP分组在网络中散布，不会增加很多额外开销。通过OPNET仿真验证LAODV协议的改进效果。

By using location information, this paper proposed a new routing protocol called Location-aided AODV (LAODV). LAODV uses location information to predefine a flooding area only in which the nodes are responsible for forwarding the control packets. This method can limit the scope of route discovery process thus reducing the control overhead. The location information is enclosed in control message to distribute in the network. At last this paper simulated the proposed protocol on OPNET Modeler,the simulation result show that LAODV is effective in reducing control overhead.
