Available in PDF, EPUB and Kindle. Book excerpt: This SpringerBrief focuses on crucial issues for device-to-device (D2D) communications within the rapidly expanding 4G LTE toward 5G system. Several critical technical challenges in D2D communications are discussed, and D2D standardization activities in 3GPP are provided. Topics range from proximity discovery and mode selection, to resource management. The authors investigate proximity detection solutions for enabling direct user equipment communication by listening to uplink transmission. The problem of mixed mode selection is demonstrated to meet multiple quality of service (QoS) requirements in D2D enabled cellular networks. Finally, the brief explores the problem of designing interference-constrained resource allocation to pair cellular user resources with potential D2D links in cellular D2D underlay, with the goal of improving spectrum efficiency. Device-to-Device Communications in Cellular Networks targets researchers and professionals working in wireless communications and networks. Advanced-level students in electrical engineering and computer science studying wireless communications and networks can also use this material as a study guide.

This book was released on 2016-06-08 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this SpringerBrief is to present security architectures and incentive mechanisms to realize system availability for D2D communications. D2D communications enable devices to communicate directly, improving resource utilization, enhancing user’s throughput, extending battery lifetime, etc. However, due to the open nature of D2D communications, there are two substantial technical challenges when applied to large-scale applications, that is, security and availability which is demonstrated in this book. This SpringerBrief proposes a secure data sharing protocol, which merges the advantages of public key cryptography and symmetric encryption, to achieve data security in D2D communications. Furthermore, a joint framework involving both the physical and application layer security technologies is proposed for multimedia service over D2D communications thus the scalable security service can be achieved without changing the current communication framework. Additionally, as the system availability largely depends on the cooperation degree of the users, a graph-theory based cooperative content dissemination scheme is proposed to achieve maximal Quality of Experience (QoE) with fairness and efficiency. This SpringerBrief will be a valuable resource for advanced-level students and researchers who want to learn more about cellular networks.

Available in PDF, EPUB and Kindle. Book excerpt: The rapid growth of mobile wireless data service continues to stimulate the investment and expansion of high-rate and bandwidth-efficient wireless network systems. High volume data traffics in modern wireless system can lead to network overload, congestion, and process delay, severely straining the limited resource and capability of cellular networks. As a result, new connection modes such as device-to-device (D2D) has emerged as potential means to alleviate traffic load on radio network controllers (RNC) and eNodeBs (eNBs). We investigated several technical aspects critical to D2D communications as an underlay within existing cellular networks. · Neighbor Discovery: One of the first steps in setting up D2D links involves pairing UEs that are in close proximity. This is accomplished during neighbor discovery process, where UEs will identify their neighbors for potential direct-link setup. To facilitate the deployment of D2D functionality to standard LTE cellular systems, it is necessary to explore neighbor discovery opportunities in existing LTE infrastructure. We developed neighbor discovery methods that are compatible with current protocols in 4G LTE networks. · Cochannel Interference Management: D2D communications can improve spectral efficiency of the cellular system by allowing D2D links share the same spectrum with cellular link. However, it also leads to a critical problem of interference management. As more advanced multi-antenna user equipment becomes widespread, precoding serves as an effective technique to combat cochannel interference. We proposed practical precoder selection strategies that utilize existing LTE codebook. To overcome channel estimation error, robust precoding techniques are further developed to guarantee cellular outage requirements within D2D underlaid cellular systems. · Resource Allocation: Resource allocation is an important topic for effective interference management across the network. For example, the eNB can allocate cellular resources to direct links that are far apart so as to reduce cochannel interference. We developed an efficient algorithm that optimizes resource allocation of D2D links across multiple D2D modes and cellular channels. With practical consideration of statistical CSI, we provided a general framework for optimizing channel and power allocation of D2D underlay with applicability to various channel fading models. Neighbor discovery, cochannel interference management and resource allocation are three successive, vital steps in setting up D2D communications in the cellular system. We proposed technical solutions to each phase with an emphasis on their compatibility with existing system architecture. Our study discloses huge potential of D2D as a practical solution to boost performances of cellular networks.

Download or read book Efficient Device to Device Communication Underlaying Heterogeneous Networks written by Xue Chen and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Device-to-Device communications have the great potential to bring significant performance boost to the conventional heterogeneous network by reusing cellular resources. In cellular networks, Device-to-Device communication is defined as two user equipments in a close range communicating directly with each other without going through the base station, thus offloading cellular traffic from cellular networks. In addition to improve network spectral efficiency, D2D communication can also improve energy efficiency and user experience. However, the co-existence of D2D communication on the same spectrum with cellular users can cause severe interference to the primary cellular users. Thus the performance of cellular users must be assured when supporting underlay D2D users. In this work, we have investigated cross-layer optimization, resource allocation and interference management schemes to improve user experience, system spectral efficiency and energy efficiency for D2D communication underlaying heterogeneous networks. By exploiting frequency reuse and multi-user diversity, this research work aims to design wireless system level algorithms to utilize the spectrum and energy resources efficiently in the next generation wireless heterogeneous network.
