基于IPv6的无线传感器网络接入设计*

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。在IPv6协议下，提出了一种大规模无线传感器网络接入国际互联网方式。本接入方式以数据应用为中心，按地理位置为无线传感器网络映射IPv6地址，由此设计了一种基于地理位置信息的顺时针逐格CGRP路由协议，并通过仿真实验分析协议的稳定性和路由分组传输成功率，最后阐述了以网关为路由接口的无线传感器网络与Internet通信机制。该接入方式既能根据IP对无线传感器网络寻址，又能降低无线传感器网络全IP化带来的高额开销，符合无线传感器应用

Wireless sensor networks connecting design under IPv6 protocol

It is a key technique to combine wireless sensor network(WSN)with current network infrastructure in WSN research. This paper proposed a access method, which connected large-scale WSN and Internet under IPv6. The access method was geared to the needs of data application, mapped IPv6 address based on geography location in WSN, and designed a geography location routing protocol named as clockwise grid routing protocol(CGRP).Simulation results show that CGRP is stable and have a high transmission success rate of routing packet. At last,described a communication mechanism which used the access gateway to communicate between WSN and Internet.The access method can not only make WSN addressable by IPv6, but also reduce the high routing overhead, which satisfy the requirements of WSN.
