Rate and Outage Trade-Offs for OFDMA Based Device to Device Communication Frameworks

Spectral Efficiency and Outage Performance for Device-to-Device Cooperation in Uplink Cellular Communication

We propose a time-division uplink transmission scheme that is applicable to Long Term Evolution Advanced (LTE-A) systems and utilizes device-to-device (D2D) cooperation. We analyze its spectral efficiency and outage performance and show that compared to existing frequency-division schemes, the proposed scheme achieves the same or better spectral efficiency and outage performance while having si...

Device-to-Device Communications for Future Cellular Networks : Challenges, Trade-Offs, and Coexistence

The steep growth in mobile data traffic has gained a lot of attention in recent years. With current infrastructure deployments and radio resources, operators will not be able to cope with the upcoming demands. Consequently, discussions of the next generation of mobile networks, referred to as the fifth generation (5G), have started in both academia and industry. In addition to more capacity, st...

Solid State Protective Device Topological Trade-offs for Mvdc Systems

Resource Allocation Optimization Based on Sum-rate Priori Iterative Auction in Device to Device Communication

We carry optimization of the cellular network and a device-to-device (D2D) underlay communication by optimizing spectral sharing through auction-based mechanism. For that, we implement reverse iterative combinatorial auction mechanism(R-ICA), in which the cellular devices laced with spectral bandwidth bid for d2d devices iteratively. We introduce a slight conjunction, and use sum rate as a prio...

Neighbor Discovery and Resource Allocation for Device-to-Device Communication

Device-to-Device (D2D) communication, which isable to access services offered by nearby devices bypassing thebase station, has been regarded as an essential part of nextgeneration cellular networks. Many advantages can be providedby this direct communication paradigm such as high data rate,traffic offloading, range extension, as well as proximity servicesand social netwo...
