Method and Apparatus for compressing a mobility header in a low power wireless network based on an IPv6

The present invention relates to a method and apparatus for compressing the mobility header of a packet transmitted and received, more particularly, Internet Protocol version 6 (Internet Protocol version 6, hereinafter 'IPv6' hereinafter) based on a low power radio network on the low-power wireless networks. A first and a is a packet transmission and reception made up of two headers containing data and transmission information of the data of the present invention, the second header is a method for compressing said header in a wireless network that leads after said first header has the the extensions to support the process, and the mobility of two header including a process and a compressed IPv6 information to determine whether or not to include compressed Internet protocol version 6 (IPv6) information, check the contained expansion header whether or not to support the mobility header When included, the bit pattern representing the first header to the compressed contained IPv6 header and the mobility support expansion header is the process of setting a bit pattern indicating that accompanying with, a defined area of ​​the second header, the mobility extension header the process of setting, and compressing the second header other than the designated region and a predetermined region of the mobility extension header Set to the bit pattern that indicates the mobility information including, and includes the step of compressing the mobility extension header other than the predetermined region of the mobility extension header. Low power Wireless Personal Area Network (LoWPAN), IPv6, header compression, mobility header, the binding update, the binding acknowledgment
