scholarly journals Interference Management by Resource Exchange for D2D Communication in Cellular Network

Scarcity in communication spectrum in cellular network is one of the major challenges faced by the service providers around the world. Many efforts were put forth to manage the efficient spectrum distribution among various cells in the network. Reusing the resources by different cells in a safe distance without interference is the current mechanism to improve spectrum efficiency. Spectrum efficiency can be even improved by reusing the resources within a single cell. Device to Device (D2D) communication, a new technology boosts the spectrum reuse inside a cell in 5G. The major hurdle in implementing D2D is in the management of interference in a highly mobile environment. This high mobility risks the life-time of a D2D link and frequent shifting from D2D mode to normal cellular mode will occur. In this paper an effort is put forward to maintain the D2D link as long as possible through a resource exchange mechanism. The exchange occurs when interference by a cellular or D2D link threatens another D2D link. This approach can improve the life-time of a D2D link and thereby improving the consistency of the network.

Abstract- Device-to-Device (D2D) communication is one of the most promising technologies to enhance user experience in 5G and beyond. Despite the huge benefit anticipated, enabling D2D in cellular network has encounter some challenges, these challenges include peer discovery and synchronization, mode selection and interference management. However, resolving these challenges promises improved service delivery, spectrum efficiency and reduced latency amongst other gains.  Attempts to enable D2D in both microwave and millimeter wave network gained some traction in recent years in a bid to enable wider coverage and utilization of the technology. Some of the research attempts, challenges and prosects are discussed in this paper.Keywords- Device-to-Device, Microwave, millimeter wave, Inter-cell Interference

A single bidirectional link is used to allow communication between two devices in the device-todevice (D2D) communication system. D2D technology has to implement with the current cellular system. As both users D2D and cellular use the same licensed spectrum for transmission the chances of interferences increases. It is challenging for researchers to find out the proper mechanism to decrease interference and maximize performances. In this paper, we try to survey the challenges and their solutions to enable D2D communication in the cellular network with low interference. Here we describe the peer discover, mode selection process and interference management with power control and resource allocation. Finally, we can say that with proper power control, spectrum slicing and resource allocation we can mitigate co-tier and cross-tier interferences.

Device-to-device (D2D) communication produces a new dimension in the mobile environment, easing the data exchange process between physically neighboring devices. To achieve an effective utilization of available resources, reduce latency, improve data rates, and increase system capacity, D2D communication utilizes nearby communicating devices. The mobile operator’s action to collect the short-range communications for maintenance of the proximity-based services and improve the performance of networks drives the development of D2D. This paper presents an extensive review of proposed solutions aiming to enhance the security in D2D communication. The main goal of the research is to present an extensive review of the recent advances in various D2D domains such as the discovery process, mode selection schemes, interference management, power control techniques and finally the mode selection for D2D applications for 5G technologies. Additionally, we highlight the open problems and identify the challenges with regard to the D2D communication problem.

Purpose The next phase of hardware technology development is focused on alternative ways to manage and store consumers’ personal content. However, even consumers who have adopted Cloud-based services have demonstrated a reluctance to move all of their personal content into the Cloud and continue to resist giving up local hard drives. This paper aims to investigate the characteristics of local hard drives and the Cloud that lead to simultaneous use. Design/methodology/approach This paper uses content analysis of online comments and ten depth interviews with simultaneous users of local hard drives and the Cloud. Findings Three factors influence the resistance to giving up local hard drives. Simultaneous users utilize local hard drives as a redundancy system and as a way to ensure the permanence of their digital content. They are unsure of the Cloud’s ability to support their content creation, management and storage activities (task-technology fit). Research limitations/implications Study findings are based on qualitative methods and thus the results cannot be considered conclusive. Practical implications The authors speculate that it is unlikely that Cloud-only will fully replace hard drives until these factors are understood and addressed by information technology developers. Cloud service providers may not be aware of how little that users understand the Cloud. In contrast to their certainty and confidence in local hard drives, simultaneous users are confused as to what the Cloud is and how it functions. This uncertainty exacerbates their risk perception and need for control. Originality/value This is the first study exploring simultaneous use of local hard drives and the Cloud with a view to understanding this behaviour in terms of the relative advantage of the incumbent technology over the new technology.

Often analysing ‘the Chinese Internet’ as a national entity, existing research has overlooked China's provincially oriented web portals, which have supplied information and entertainment to substantial user populations. Through the lenses of the critical political economy of media and critical media industry studies, this article traces the ascendance of China's provincial web from the late 1990s to the early 2000s by analysing industry yearbooks, official reports, conference records, personal memoirs, archived webpages, and user traffic data. We uncover interactions between Internet service providers, legacy media organizations, commercial Internet companies, and the central and local governments – each driven by discrete economic interests, political concerns, and imaginaries about the new technology. Delineating the emergence and consolidation of China's provincial web, our study foregrounds the understudied political economy of online content regionalization at scale. Further, it sheds new light on Chinese media policy, Internet governance, and Internet histories, especially the widely noted conservative turn of online cultures after the mid-2010s.
