At present, device terminal broadcasting allows devices in the distributed network to act as transmitting relays to each other and reach a massive ad hoc network of networks that is different from the previous cellular architecture that faces technical challenges. Therefore, this article explores the application of a cellular-based two- layer network system that includes a base station (BS) cellular layer, such as cellular-to-device communication and communication between devices. In the proposed two-tier cellular-based network system, user data is transmitted through other users' devices to implement the privacy protection that is lacking in prior communication between devices in cellular systems. To ensure a negligible impact on the performance of current communication between devices, a two-layer network is assimilated to autonomous interference management schemes and associated resource allocation schemes. The findings from this review provide an overview of the major challenges in two-tier networks and propose a two-tier cellular-based system in which user data is routed through other users' devices to implement privacy protection.

Introduction With the launch of several smart handheld devices, mobile broadband user needs are experiencing unrivaled growth. The sharp rise in bandwidth systems, such as sharing media files and streaming videos, is already pushing the limits of current cellular- based systems. The ever-increasing demand for advanced data rates and capabilities requires unconventional thinking for a new generation of cellular network systems [1]. Mobile network-based networking means a new class of wireless communication techniques in which network nodes help each other to transfer data to realize spatial benefits. This new communication paradigm promises a significant increase in performance in terms of transmission range, communication reliability, efficiency, spectral and system capabilities [2]. Cooperative comm unication has been extensively explored in literature and static broadcasting of terminals, which primarilzy involve the deployment of low- power base stations to support data communication between destination and source. Device-to-Device (D2D) network Communication in cellular network systems brings improvements in cellular systems, but full collaboration capability can only be achieved by application transfer devices. The term network communication between devices therefore refers to a portable wireless device or any other mobile phone with mobile connectivity, such as a laptop, tablet, etc. which is owned by an end user. Device communication allows devices in the network to function as relay relays and to implement a massive ad hoc network [3]. This is, of course, probable with the capabilities of cellular based network systems on device-to-devices, which allows two nearby devices to interconnect each other in the licensed cellular bandwidth without a connected base station or a limited base station (BS) association. It is clearly a dramatic departure from orthodox cellular architecture. In the first four versions of cellular-based network systems, the D2D communication options have not been decided. This is mainly because it is primarily int ended as a tool to reduce the costs of providing local services which were negligible in the past on the basis of market data on cellular transactions [4]. For this reason, operators' access to D2D features has recently changed due to numerous developments in the wireless market. The number of awareness-raising applications and services is growing rapidly. These applications need to communicate with neighboring devices as well as possessing location discovery features. Therefore, the availability of such features would reduce the communication fee between the devices. D2D features can also play a lively role in mobile cloud computing, enabling operational sharing of application resources, computational social content, energy spectrum, and so on. For users who are close to each other. In addition, service providers can use the D2D capabilities to use some off-network capabilities in a remote area such as campuses by enabling direct communication between mobile phones and other related devices [5]. In addition, D2D capabilities can be effectively used in communicating natural disasters. In the case of a hurricane or an earthquake, an emergency network based on data communication can be deployed using D2D functions in a short space of time and replace the broken communications network and Internet infrastructure. In the current trend, previous technologies and systems like Bluetooth or WiFi bring some D2D communication capabilities. However, it operates in an unlicensed band and the
