摘要
无线传感器网络节点的资源非常有限,如果能够对IPv6报头进行压缩可以在较大程度上减小数据传输量,提高IPv6传感器网络的整体性能。通过对6LoWPAN报头压缩方案的研究,并结合无线传感器网络的特点和实际需求,在已有无线传感器网络底层协议和基本IPv6协议栈基础上,设计并实现了一种支持对跳数限制压缩的IPv6报头压缩方法。实验结果表明,报头压缩可以有效节省网络能耗,降低丢包率,减小数据传输时延。
As the resource of WSNs nodes is limited, a scheme of IPv6 masthead compression is proposed for significantly reducing the amount of data transmission and improving the overall performance of IPv6 sensor networks. Under the research of 6LoWPAN（IPv6 over Low power WPAN） masthead compression, in combination with characteristics and practical require ments of the wireless sensor networks, a IPv6 masthead compression scheme supporting hop limit compression was designed and realized, based on the existing basic protocols of IPv6-WSN. The experimental results validate that the masthead com pression can effectively reduce energy consumption, packet loss rate and the delay of packet delivery.
