In this paper, we propose an adaptive congestion control scheme to control congestion caused in wireless/mobile access networks of ubiquitous computing environment. Significantly, this scheme includes a new reverse congestion avoidance phase, which can classify packet loss due to bit error or network congestion. Also, it includes a new slow stop phase which can minimize an wasted bandwidth due to previous congestion control schemes. And, this scheme controls network congestion more adaptive than previous congestion control schemes by a new method of congestion measurement and various phases in the adaptive congestion control scheme. The new method of congestion measurement classifies degree of congestion by a relation of the number of loss packets and increment size of a congestion window. This scheme is designed based on DCCP(Datagram Congestion Control Protocol) being proposed by IETF(Internet Engineering Task Force). In our simulation, this scheme provides a good bandwidth throughput not in wireless/mobile access networks but also in wired networks.
