Adaptive timer-based TCP control algorithm for wireless system

Supporting heterogeneous services are mandatory for 3G and beyond wireless systems, using the data transmission protocol such as transmission control protocol (TCP) designed for wired systems might not be suitable for wireless systems. In this paper an adaptive timer based control algorithm is proposed to improve the TCP performance, the algorithm can dynamically change round trip time (RTT) estimation values and adapt to current bandwidth conditions. Because the correct retransmission time out (RTO) values are calculated from a new adaptive RTO estimation value spurious timeouts problems due to incorrect RTO values caused by bandwidth variations can be resolved and TCP performance over wireless can be improved.
