The AIP Proceedings article template has many predefined paragraph styles for you to use/apply as you write your paper. To format your abstract, use the Microsoft Word template style: Abstract. Each paper must include an abstract. Begin the abstract with the word “Abstract” followed by a period in bold font, and then continue with a normal 9 point font.Wireless networks are widely used in Internet of Things (IoT) , Ad-hoc networks, Sensor networks. An important problem need to be solved in wireless networks is there is no reliable transport layer protocol at present. TCP (Transport Control Protocol) is the that provides reliable end to end data delivery. It was originally designed primarily for wired networks. Buffer queue overflow at the bottleneck nodes (also known as congestion) is the main reason for packet loss and retransmission timer timeout in wired networks. The main problems are high BER, precarious wireless channel and user mobility in wireless networks. Therefore, traditional TCP performs badly in the wireless network. But study on traditional TCP is very important. We can promote TCP algorithm in wireless networks through the study of traditional TCP. In this paper, we designed a series of experiments based on the NS2. We focus on the different performance of the traditional TCP used in the wireless networks and wired networks. We tried to analyze the reasons for the relevant data results and put forward our own opinions on how to design TCP mechanisms.
