Performance analysis of MTC traffic on TCP in 5G wireless network

Abstract

Abstract 5G wireless network carry different type of traffic generated by various applications running on the hosts. Some of the traffic carried by 5G broadband network is human-type communication (HTC) and machine-type communication (MTC) along with conventional data traffic due to HTTP, FTP, and video streaming applications. MTC wireless communication is made up of sensors, actuators, and other devices called massive machine-type communication (mMTC), not directly operated by humans. These devices are connecting the base station at any given time that leads to randomness in the traffic flows. Thus, the data traffic generated by MTC devices can be periodic or event-triggered [1]. In this research paper, tried to extend the work proposed in [1] by considering two types of traffic, (i) periodic traffic generated by MTC and (ii) network responsive traffic generated by transmission control protocol (TCP). Traffic management at the base station is made by a RED router. A model based traffic performance analysis has been conducted to study the dynamics of sender window, rtt delay, queue dynamics, probability of packet losses and the effect of MTC load on TCP at the ingress of the router. This helps in understanding the performance of 5G wireless network, tuning the router parameters and in providing guaranteed quality of service (QoS) by optimising the network resources. Graphical and statistical analysis has been presented using Matlab programming.
