SPRINGERBRIEFS IN COMPUTER SCIENCE COOPERATIV...

This brief examines current research on cooperative device-to-device (D2D) communication as an
enhanced offloading technology to improve the performance of cognitive radio cellular networks.
By providing an extensive review of recent advances in D2D communication  the authors
demonstrate that the quality of D2D links significantly affects offloading performance in
cellular networks  which motivates the design of cooperative D2D communication. After
presenting the architecture of cooperative D2D communication  the challenges of capacity
maximization and energy efficiency are addressed by optimizing relay assignment  power control
and resource allocation. Furthermore  cooperative D2D communication is enhanced by network
coding technology  and then is extended for broadcast sessions. Along with detailed problem
formulation and hardness analysis  fast algorithms are developed by exploiting problem-specific
characteristics such that they can be applied in practice.
