Abstract: Aiming at the deficiency of the existing local repair technology, this paper proposes a new local repair scheme based on link failure. It is on the basis of AODV local repair and concerns about status of nodes. Link failures are classified and different methods are adopted for different link failures. Simulation result indicates that the improved technology can promote network performance by reducing route setup time and control packets.

Key words: Mobile Ad hoc Network(MANET), routing protocol, link failure, local repair

摘要： 针对已有移动自组网本地修复技术的不足，以AODV路由协议的本地修复技术为基础，考虑网络节点状态的变化，提出一种基于链路故障的本地修复技术，对链路故障进行分类，对不同类型的故障采取不同的修复方法。仿真结果表明，改进的本地修复技术可以有效减少路由建立时间并控制分组开销，提高了网络性能。
