TCP-PCP: A Transport Control Protocol Based on the Prediction of Congestion Probability over Wired/Wireless Hybrid Networks

Many of packet loss as a result of factors other than congestion impact the performance of TCP in wired/wirelss hybrid networks. Firstly, this paper proposes one concept of congestion probability (CP) and analyzes the correlation of CP and network state. Then a transport control protocol named as TCP-PCP is proposed, which is based on the prediction of congestion probability instead of single loss event. Depending on the ECN mechanism, TCP-PCP calculates the value of CP by analyzing some latest loss events. The TCP-PCP sender´s behavior is controlled by the change of CP value. Simulation results show that TCP-PCP can improve TCP performance more efficiently than Westwood and Jersey.
