In this paper, unlike the current end-to-end congestion control mechanism such as TCP that only reduces its traffic in the presence of congestion, we propose a new wireless congestion control framework, in which a mobile station's MAC-layer tries to increase its available wireless bandwidth in the presence of incipient congestion when available bandwidth can be increased without affecting other flows in a cell. In our framework, wireless congestion is classified into channel congestion, queue congestion, and global congestion. In order to control congestion timely, the mobile station's MAC-layer decides whether available bandwidth should be increased or incoming traffic should be reduced based on the congestion type. In addition, thanks to the MAC-layer's ability to better observe the wireless channel condition, the wireless congestion, which is considered more important than the wired congestion due to its limited bandwidth, can be better handled when the path of a mobile station's connection spans wired network.
