The millimeter wave (mmWave) communication is now considered as a predominant technology for fifth generation (5G) systems to meet the surging needs of traffic by ensuring massive bandwidth with high dimensional antennas. However, transmission control protocol (TCP) analysis due to mobility is still complex in nature. In addition, packet trip length, i.e., round trip time (RTT) and length of congestion window (CWND) need to be more investigated. In this paper, the executed framework of mmWave channel modeling has been inspected with ns-3 simulator. In this research, we consider several mobility models (e.g., constant mobility, Gaussian Markov, and random direction 2D) for a UE who is using mmWave link to communicate with eNB to transfer its traffic. These TCP analysis may be utilized to exhibit the potential of 28 GHz mmWave band and its worthy for the design of future 5G networks.
