摘　　要：轻量级IPv6邻居发现协议是6LoWPAN(IPv6 over Low power Wireless Personal Area Network,轻量级IPv6协议)的重要补充,旨在解决6LoWPAN无线传感网络初始化和网络维护过程中普遍存在的节点高消耗问题。文中归纳并总结了邻居发现轻量化的必要举措,在此基础上,提出了一套轻量级IPv6邻居发现协议在基于Linux操作系统的边界网关中的实现方案。通过在内核中邻居发现模块添加新特性,边界网关将负责处理大量原本需要传感节点分担的组网任务和网络维护任务,大大降低了域内节点开销。通过对原型系统的功能测试,方案完全符合协议标准,简单高效,并做到了与标准IPv6邻居发现协议的兼容。The 6LoWPAN-NDP （6LoWPAN Neighbor Discovery Protocol） is an indispensable supplement to the 6LoWPAN,which fo-cuses on the conservation of nodes＆#39; energy and network resource in 6LoWPAN during the network initialization and maintenance. In this paper,the necessary measures of neighbor discovery lightweight are summarized. Based on it,put forward a realizing scheme of a light-weight IPv6 neighbor discovery protocol in border router based on Linux operating system. Through adding the new feature in neighbor discovery module in kernel,the border router will handle with the large amount of networking tasks and network maintenance tasks which originally needs sensor node share,greatly reducing the node overhead in domain. The benchmark test shows that the border router de-signed is up to standard with the 6LoWPAN-NDP. Its high efficiency and compatibility makes it available to apply in some real applica-tions.
