Summary: Since the traditional TCP is tuned to perform well in wired networks and stationary nodes environments, its performance is deteriorated in wireless networks that cause many errors and disconnections. There have been some researches such as Snoop and M-TCP to improve the TCP performance in wireless network environment. In this paper, we propose an “enhanced mobile TCP (EM-TCP)” by combining Snoop and SH-TCP in M-TCP to improve the performance of TCP connections when a mobile node uses Internet service via a roadside base-station. We implement the proposed algorithm EM-TCP using ns-2 (Network Simulator) and perform simulation of a DSRC-based ITS system adopting EM-TCP, Snoop and ordinary TCP. Simulation results show that the EM-TCP improves the TCP performance in wireless network environments better than the Snoop and ordinary TCP.
