Security-Aware Device-to-Device Communications Underlaying Cellular Networks




Security-Aware Device-to-Device Communications Underlaying Cellular Networks
Springer | Communication Networks | July 12, 2016 | ISBN-10: 3319324578 | 73 pages | pdf | 1.82 mb


Authors: Zhang, Aiqing, Zhou, Liang, Wang, Lei


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.

Encyclopedia of Terminology for Educational Communications and Technology (Repost)




Encyclopedia of Terminology for Educational Communications and Technology By Rita C Richey
2013 | 370 Pages | ISBN: 1461465729 | PDF | 2 MB



​The Encyclopedia of Terminology for Educational Communications and Technology is a volume of scholarly definitions and short discussions of approximately 180 key terms of the field. Each 200-500 word entry includes material such as the salient attributes of the term, any alternative views and interpretations of the term, and future trends. The definition discussions are supported with relevant literature from educational communications and technology and related fields, such as communications or educational psychology. Individual signed entries are written by over 50 established scholars from throughout the field and throughout the world. The terms included in the encyclopedia cover the many topics addressed by the field’s practitioners and scholars. They encompass six general categories of educational technology content – foundational subjects, instructional design, technology and media, analysis and evaluation, management and organizational improvement, and research and theory.​

Device-to-Device Communications in Cellular Networks




Device-to-Device Communications in Cellular Networks
Springer | Communication Networks | May 31, 2016 | ISBN-10: 3319306790 | 90 pages | pdf | 2.3 mb


Authors: Wang, Li, Tang, Huan


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.
