Abstract

This  article  presents  a  Multilayer  Header  Compression  scheme  for VoIP  packets  in  802.11  wireless  networks  that  does  not  require  context synchronization of compressor and decompressor units. The reduction of the header size is accomplished through the static field compression of the RTP/UDP/IP headers in conjunction with an 8 bit virtual addressing in the 802.11 MAC layer. Considering the RTP/UDP/IP/MAC header fields, this scheme allows  48%  header  compression  efficiency  compared  with  41%  provided by the CRTP and RoHC schemes. Given that our proposal does not require context synchronization, the decompressor will regenerate the headers even in high packet loss rate conditions.
