IPv6 header compression algorithm supporting mobility in wireless networks

This paper proposes a new compression algorithm supporting IPv6 mobility in wireless communications, called the IPv6 header compression algorithm. The idea of the algorithm is to provide an effective compression rate to support the mobility and the spectral efficiency required in wireless networks. The data link layer and the physical layer based on the OSI model are thus considered. To support the mobility it is assumed that any change of other fields in an IPv6 header except care-of-address disconnects the call. The address assignment method and LZW coding delivers significant compression of the long IPv6 header for the initial connection. After the initial communication, the algorithm provides compression through comparator coding and LZW coding. The algorithm's performance is evaluated using both analytic techniques and computer simulation.
