1、摘要进入21世纪以来，随着无线通信技术和网络技术的发展，信息传播无论从速度还是广度上都有了质的飞跃。人们希望可以不受时间和空间的限制，自由流畅地进行信息的传递交流。低速无线个域网正是未來多域异构的无线网络的重耍组成部分它不仅可以有效地解决最后1米的无线接入问题，而且能够在个人空间范围内为用户提供丰富业务类型的无线连接,随时随地的为用户提供信息传输、协同和处理。低速无线个域网不但要求传输技术能够适应复朵的室内无线环境，具有较高的抗频率选择性衰落和抗干扰能力，较大的系统容量，还必须具有低功耗和低复杂度的特点。针对低速无线个域网的特点，在AODV基础上设计并实现
2、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、带宽占用等方面貝有很强的优势。关键词:低速无线个域网；路由协议;AODVAbstractInthe21stcentury,withthedevelopmentofwirelesscommunicationtechnologyandnetworktechnology,informationdissemin
