Abstract

TCP application in wireless HCI environments communicates to each other frequently through wireless networks. Therefore, it is important that significant TCP performance is guaranteed in wireless network. TCP New Jersey, known as the best existing scheme in terms of goodput in wireless networks, improves wireless TCP performance using the available bandwidth estimation at the sender and the congestion warning at intermediate routers. Although TCP New Jersey achieves 17% and 85% improvements in goodput over TCP Westwood and TCP Reno, respectively, we further improve TCP New Jersey by exploring enhanced available bandwidth estimation and suitable error recovery mechanism. Hence, we propose TCP NJ+. It outperforms other TCP variants by 19% to 104% in terms of goodput even when the network is in bi-directional congestion. Hence TCP NJ+ can provide the best services to user in wireless HCI environments.
