摘要
移动自组网是由一组带有无线收发装置的移动终端组成的自治通信系统。煤矿井下移动自组网可应用于矿井的监控管理系统、数据采集系统或者应急通信系统。移动自组网的路由方案主要包括表驱动(Proactive)和按需驱动(Reactive)两种,AODV是一种代表性的按需驱动算法。文中介绍了利用辅助路径基于AODV的一种矿井移动自组网的路由恢复算法,给出了辅助路由算法的性能测评方案。
Ad-hoc Network is an autonomous communication system composed of a group of mobile terminals with radio transceiver. Ad-hoc network is a technology applicable for monitoring and controlling system, data collecting system or emergency communication system for underground coal mine. According to its routing method, Ad-hoc network can fall into two categories： proactiveand reactive. AODV is a typical reactive routing method. This paper proposes an AODV-based routing recovery mechanism using secondary path in Ad-hoc network for underground coal mine, and presents some principles for evaluating the performance of the AODV-based route recovery mechanism using secondary path.
