The Transmission Control Protocol (TCP) experiences severe performance degradation within wireless mobile ad hoc networks. The main reason is that the regular TCP does not discriminate packet losses due to medium error and disconnection (mobility) from congestion-induced losses. This paper presents the general ideas of the proposed end-to-end approach for enhancing TCP in this critical environment. The base of this approach is to involve only the end nodes in the congestion control performed by TCP. In other words, no specific cooperation from intermediate nodes is needed. Rather, a TCP sender monitors the network state and uses this input to react correctly. Using this approach, different monitoring techniques may be used to infer the internal network state.
