Transmission Control Protocol (TCP) is the most commonly used transport protocol on the internet. The performance of TCP in wireless network is not satisfactory as it was originally designed for wired networks. This paper proposes Dynamic DCF Backoff Algorithm(DDBA) to improve the throughput of TCP in wireless mobile environment. The proposed DDBA minimizes TCP Instability problem initiated by wrong link failure information from the source node. The simulation in NS2 shows improved TCP performance in Grid, Cross and Random topology of wireless networks incorporating mobility of nodes.
