Research of the Network Layer Frame Header Compression Based on ISA100.11a Protocol

针对无线传感器网络节点的资源非常有限的问题,为了使IPv6帧能够在ISA100.11a协议下高效的传输,提出了帧头部压缩方法。在ISA100.11a协议的网络层中设计了IPv6帧头部压缩模块,对IPv6固定帧头部进行了压缩。使用sniffer抓包工具获取IPv6帧并进行分析,实验结果表明,IPv6帧头部压缩模块起到了很好的作用,证明了帧头部压缩方法在ISA100.11a协议中的可行性。

Due to the nodes of wireless sensor networks have very limited resources, in order to make the IPv6 frames can be transmitted efficiently in the ISA100.11 a protocol, the frame header compression method is introduced. By designing the IPv6 header compression module in the network layer of the ISA100.11 a protocol, the IPv6 fixed frame header is compressed. By using sniffer caught tool IPv6 frame is obtained and carries on the analysis. The test results show that, IPv6 header compression module plays a very good role, proves the feasibility of the header compression method in ISA100.11 a protocol.
