TCP suffers from low throughput in mobile ad hoc network due to its inability of distinguishing various causes of packet losses. Explicit Link Failure Notification (ELFN) has been proposed to improve TCP performance in mobile environment against packet losses due to link failure. However, link failures in ad hoc networks are not only resulted by node mobility but also severe contention. In this paper, we adopt a cross-layer approach based on MAC layer information to inform the contention level along a path to the sender, and the sender can adjust its sending rate to decrease severe contentions. We attempt to prevent severe contention occurrence at an early stage, thus reduce the number of link failures. Simulation results generated by ns2 shows that the proposed approach help improve TCP performance in mobile ad hoc networks.
