摘　　要：针对低速无线个域网的特点,在AODV基础上设计并实现了一种考虑节能、对硬件资源要求低、收敛速度快的路由协议,该协议包含"反馈控制标志"、"上游节点寻路"、"只限广播的扩展环搜索"等优化策略。进一步给出路由协议模型、报文格式以及算法实现流程,与同类协议进行了性能比较。实验结果表明,协议在存储资源消耗、链路修复、带宽占用等方面具有很强的优势。In this paper, an energy-aware fast convergence routing protocol with low requirements of hardware resources is proposed for low-rate wireless personal area network （LR-WPAN）. We also design some optimization mechanisms including ＂feedback flag＂, ＂upper node routing＂, ＂broadcast-restricted ring search＂ to improve the protocol performance. Furthermore, routing modules, packet format and algorithms are described in details. Finally, we have implemented it in our testbed and compared with several other typical protocols. The experiment results show that it can significantly improve the system performance such as storage consumption, link recover speed and bandwidth occupation.
