METHOD AND APPARATUS FOR COMPRESSING A MOBILITY HEADER IN A LOW POWER WIRELESS NETWORK BASED ON AN IPV6

摘要

A method and an apparatus for compressing a mobility header in a low power wireless network based on an internet protocol version 6 are provided to move a mobile node or a mobile router having a 6LoWPAN(Low power Wireless Personal Area Network) function with low power by reducing a length of a signaling packet. A control unit checks whether a second header includes compressed internet protocol version 6 data(805). The control unit checks presence of a mobility header(810). The control unit sets a pattern of a dispatch header including the mobility heater(815). The control unit sets a next header field of the compressed internet protocol version 6 header as a bit pattern '00'(820). The control unit sets the residual fields. The control unit checks whether data of a transmitting packet are binding update data(825). The control unit sets 0th bit of the mobility header as '0'(830). The control unit sets the residual bits of the mobility header(835). The control unit generates a 6LoWPAN header for supporting mobility(840).
