ABSTRACT：The implement of header compression algorithm in Ah hoc IMD can greatly increase the transmission efficiency of VoIP packets. An IP/UDP/RTP header compress algorithm for the use of Ad hoc network is firstly introduced in this article, then based on the discussing of the data process flow in Ad hoc network test bed, the data process flow is amended and the header compress algorithm is applied in IMD. In succeed, through compare, we analyze the transmission performance of header compress algorithm for timing VoIP packets.
