TCP-FIT — A novel TCP congestion control algorithm for wireless networks

Abstract

The Transport Control Protocol (TCP) has been widely used in wired and wireless Internet applications such as FTP, email and HTTP. However, performances of traditional TCP congestion algorithms degrade significantly when deployed over wireless networks. In this paper, we proposed an improved TCP congestion control algorithm for wireless networks, named TCP-FIT, and compared its performance with existing state-of-the-art congestion control algorithms as well as an application layer Parallel TCP scheme. Experiment results show significant performance improvement, good fairness and lower end-to-end latency for TCP-FIT.
