Cellular traffic: This article studies the mobile cellular network. Mobile radio networks have traffic issues but public switched telephone networks do not. Important features of cellular traffic include quality of service targets, traffic capacity and cell size, spectral efficiency, traffic capacity, and channel holding time analysis [12]. Telegraphic engineering in telecommunications network planning secures that network costs are reduced without compromising the quality of service delivered to the user of the network [13]. This field of engineering is based on probability theory, as well as other telecommunications networks. A moving mobile handset will record a signal strength that differs. Signal strength is a slow fading, fast fading, and interference from other signals, resulting in degradation of the carrier-to-interference ratio (C/I). A high C/I ratio provides quality communication. A good C/I ratio is reached in cellular systems by using optimum power levels [14]. Creating excessive interference the carrier power must be too high, and reducing the C/I ratio for other traffic and also reducing the traffic capacity of the radio subsystem. When carrier power is too low, C/I is too low [15].

In Reference 22, authors analyze the resource sharing in a D2D communication overlaying cellular system, in which both cellular traffic and D2D traffic use the same resources, and the system aims to optimize the total throughput over the shared resources while fulfilling possible spectral efficiency restrictions and power constraints.

The importance of cellular network performance has attracted significant work. A considerable amount of work has been done on cellular traffic characterization and traffic performance in terms of traffic volume (Falaki et al., 2010), diversity (Falaki et al., 2010; Shepard et al., 2010), network performance (Kilpi & Lassila, 2006; Mattar et al., 2007; Romirer-Maierhofer et al., 2010; Shafiq et al., 2013), temporal and spatial variation (Paul et al., 2011; Shafiq et al., 2012). Similar studies have been undertaken in other countries and contribute solutions to the network under study. In China, for example, the analysis of 3G traffic performance shows important characteristics of the networks’ diversity (Hu et al., 2015), whereas in (Laiho et al., 2005) an in-depth analysis of 3G traffic has been taken and advanced optimization methods have been proposed. There are quite a few numbers of similar papers published in different magazines and journals.
