Performance of Transport Control Protocol (TCP), designed for wired networks, degrades significantly over wireless links and provides abysmal throughput because TCP assumes that all packet losses are caused by congestion. However, in wireless ad-hoc networks, packet losses could be due to several reasons such as link loss, node mobility, and faulty nodes, to name a few. Current techniques for improving TCP do not consider packet drops by faulty nodes. The authors propose a novel idea of distinguishing between wireless and congestion losses by using the concept of Kleinrock's "Power" metric. Based on this idea they propose two reliable transport protocols, TCP-Monet and TCP-Sec, that classify packet losses based on current connection status and react accordingly.
