基于IPv6的WSN边界路由器设计
|
摘要
针对无线传感器网络与IPv6网络互联,在分析现有接入方式不足的基础上设计了一种基于IPv6的无线传感器网络边界路由器。主要阐述了边界路由器的硬件和软件实现,重点介绍了基于IPv6的无线传感器网络协议栈适配层的设计。通过数据包分片与重组机制以及报头压缩机制,协议栈适配层实现了IPv6数据包在IEEE 802.15.4链路中的传输。实验结果表明,该设计方案实现了无线传感器网络与IPv6网络的无缝融合,数据传输稳定可靠,具有应用价值。
Based on the disadvantage of the existing access methods, an IPv6-based WSN(Wireless Sensor Networks) border router is designed to achieve the integration of WSN and IPv6 networks. The board router hardware and software implementations were mainly elaborated. The adaptation layer of the IPv6-based WSN protocol stack was focused on. The transmission of IPv6 packets over IEEE 802.15.4 networks has been achieved through the packet fragment reassembling and header compression mechanisms. The results show that the seamless fusion of wireless sensor networks and IPv6 networks can be achieved. The data transmission is reliable, and the design has application value.
