PROBLEM STATEMENT

Most traffic that flows over the Internet makes use of the Transmission Control Protocol (TCP), and wireless multihop networks are one way to provide access extension. TCP is one of the pro-tocols designed for wired networks and exhibits severe degradation in multihop networks. It was designed to provide reliable end-to-end delivery of data over unreliable networks and has been carefully optimized in the context of wired net-works. For example, large TCP default window sizes that are appropriate for a wired network are too large for wireless links in multihop net-works. Another type of traffic becoming more preva-lent in homes and institutions is voice over Inter
