Firstly, the limitations and challenges of TCP protocols in wireless access networks are analyzed. Then, the TCP optimization schemes in wireless access networks are sorted out, which are mainly classified into single-path TCP optimization and multipath TCP optimization, simultaneously the comparative analysis of various optimization schemes is summarized. Finally, the development directions of TCP protocol optimization are presented. %U https://journal.bupt.edu.cn/EN/10.13190/j.jbupt.2018-280
