A Practical Adaptive Pacing Scheme for TCP in Multihop Wireless Networks

The authors introduce and evaluate a feasible end-to-end congestion control algorithm for overcoming the severe deficiencies of TCP in IEEE 802.11 multihop wireless networks. Their approach, which they denote as TCP with Adaptive Pacing, implements rate-based scheduling of transmissions within the TCP congestion window. The TCP source adaptively sets its transmission rate using an estimate of the current out-of-interference delay and the coefficient of variation of recently measured round-trip times. TCP-AP retains the end-to-end semantics of TCP and does neither rely on modifications at the routing or the link layer, nor requires cross-layer information from intermediate nodes along the path.
