Cross-layer Optimized Design for TCPW Protocol

The performance of traditional TCP protocol is much discounted over hybrid network.TCP Westwood(TCPW) protocol is an end-to-end solution based on bandwidth estimation.Aiming at the problem of inaccurate bandwidth estimation for TCPW protocol,this paper proposes a cross-layer optimized design,uses times of Request To Send(RTS) of Media Access Control(MAC) layer as a congestion metric.Simulation results show that this optimized design can improve performance of the total throughput and fairness respectively by 23.8% and 2.5% than TCPW protocol.
