%X Ad hoc network is a kind of self-organizing network, and it requires no infrastructure, nor any central con- trol. It can be rapidly constructed under emergency conditions. A major problem for IEEE802. 11-based ad hoc network is the super high link-layer delay when the channel is fully loaded, which prevents upper-layer protocols from working properly. By introducing modifications on both transport layer and link layer, we propose a congestion control algo- rithm that employs congestion window, data packet lifetime management, and packet priority control. The algorithm significantly reduces the link-layer delay and greatly improves the throughput of the network under such conditions.
