In the scope of wireless network, traditional TCP congestion control mechanism exhibits low bandwidth utilization and poor reliability, so a congestion control protocol adaptable to the characteristics of wireless network is worthy of investigation. An intelligent gateway model with network boundary access control features has been established based on the analysis of TCP protocol. To optimize this model, loss differentiation mechanism was added and additive increasemechanism has been improved, and finally NS-2 emulation was performed with an optimized TCP Westwood algorithm (TCPW-I). It is demonstrated that TCPW-I can distinguish packet loss causes and postpone the occurrence of TCP congestion to effectively improve the throughput of TCP in wireless network circumstances, maintaining satisfying TCP friendliness and fairness of its own.
