中文摘要：
无线传感器网络（WSN）与现有网络基础结合是WSN研究中必须解决的技术问题之一．本文分析了WSN接入以太网存在问题，总结了基于IEEE 802．15．4的无线传感器网络的特点．设计了一套这种无线传感器网络与以太网间的接入系统．该系统遵循6LoWPAN规范，解决了WSN节点的IPv6地址自动配置问题；设计了接入网关；定义了信息与控制数据格式．实现了一套应用验证系统并进行了实验；对网络性能进行了分析．实验结果表明该设计简单有效，能够完成WSN的高效接入，在工程实践中具有实用价值．
英文摘要：
It is a key technique to combine Wireless Sensor Network （WSN） with current network infrastructure in WSN research. By analyzing the current issues of WSN access to Ethemet and summarizing the characteristics of WSN based on IEEE 802.15.4, a system for IEEE 802.15.4 based on WSN access to Ethemet is designed under IPv6. This system obeys 6LoWPAN specification, and implements the structure of IPv6 over IEEE 802.15.4. To distribute global unicast address for FFD nodes, a tree based address distribution algorithm is demonstrated. A gateway is designed for this system, and the format of controller-packet is introduced, too. A experiment system in miniature is implemented to validate this design. We also analyze the performance of this system. The experiment indicate that it is useful and effective.
