Standard congestion control cannot detect link failure losses which occur due to mobility and power


scarcity in multi-hop Ad-Hoc network (MANET). Moreover, successive executions of Back-off algorithm


deficiently grow Retransmission Timeout (RTO) exponentially for new route. The importance of detecting


and responding link failure losses is to prevent sender from remaining idle unnecessarily and manage


number of packet retransmission overhead. In contrast to Cross-layer approaches which require feedback


information from lower layers, this paper operates purely in Transport layer. This paper explores an end-


to-end threshold-based algorithm which enhances congestion control to address link failure loss in


MANET. It consists of two phases. First, threshold-based loss classification algorithm distinguishes


losses due to link failure by estimating queue usage based on Relative One-way Trip Time (ROTT).


Second phase adjusts RTO for new route by comparing capabilities of new route to the broken route


using available information in Transport layer such as ROTT and number of hops.
