摘要
6Lo WPAN(IPv6 over Low-Power Wireless Personal Area Networks)定义了IPv6报文如何在IEEE802.15.4网络上传输。其中难点主要在于适配层的报头压缩,这对于增大有效负载的空间非常重要,因为IEEE802.15.4留给上层协议的空间只有81字节左右。简单介绍了了6Lo WPAN的几种现有的报头压缩算法,同时着重研究了一种通用的报头压缩算法6LOWPAN_GHC(以下简称GHC),并进行了实验验证。GHC可以看做是对通用报头及类报头有效载荷的一种补充算法,这样就不需要为新报头或者类包头有效载荷定义新的压缩规范了。
This paper introduces several existing header compression algorithms of 6Lo WPAN,and moreover,and focuses on studying a generic header compression algorithm called 6LOWPAN_GHC(hereinafter referred to as GHC),which is experimentally verified later.GHC is a simple addition that enables the compression of generic headers and header-like payloads,without need to define a new header compression scheme for each such new header or header-like payload.
