Ad Hoc网络是由一组带有无线收发装置的移动终端组成的一个多跳临时性自治系统。网络中的每个移动终端是主机也是路由器，根据路由算法参与路由的建立和分组转发工作。 本文说明了Ad Hoc网络的特点和研究热点，简要介绍了传统的Ad Hoc网络路由协议和利用地理位置信息的Ad Hoc网络路由协议，其中详细叙述了基于地理位置信息的路由协议GPSR。然后在GPSR的基础上提出一个新的基于地理位置信息的路由协议GLFR。其中，我们通过增加路由探测的过程，达到了对原路径进行减枝的目的，从而减少了路由跳数和路由距离。最后在eclipse平台上编写java模拟程序考查GLFR的网络性能。结果表明，与GPSR相比，GLFR在平均路由跳数和平均路由长度上要优于GPSR。
Ad Hoc Network is a multi-hop temporary self-organized system, which consists of a set of mobile terminals with the radio devices. Each mobile terminal is both a host and router, performing route setup and packet forwarding according to a routing algorithm. This paper firstly reviews the characteristics and design constraints of Ad Hoc Network, simply introduces tranditional and geographic routing protocols in Ad Hoc Network. We mainly review GPSR, a geographic routing protocol in detail. Secondly, we propose a new geographic algorithm GLFR which is based on GPSR. In GLFR, we add router discovery process to eliminate hops in router path, resulting in less router hops and router distance. Lastly, we evaluate the performance of GLFR with eclipse in java. The result concludes that, compared to GPSR, GLFR reduces the average router hops and average router distance.
