SPRINGERBRIEFS IN ELECTRICAL AND COMPUTER ENGIN...

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.
