Simulation results are presented to validate the performance of the proposed algorithm where the results are compared with the existing works in literature as well as with a sub-optimal power optimization solution.Abstract:
In this paper, we consider an orthogonal frequency division multiplexing based device to device network. The communication between source and destination is facilitated by a dual-hop transmission under amplify and forward relaying protocol. The sum throughput of the system is maximized with joint optimization over power allocation at each transmitting node and sub-carrier pairing over two hops. A dual decomposition based solution is proposed subject to separate transmit power constraint at each node. Simulation results are presented to validate the performance of the proposed algorithm where the results are compared with the existing works in literature as well as with a sub-optimal power optimization solution.read more

Resource Optimization for Cognitive Radio Based Device to Device Communication Under an Energy Harvesting Scenario
TL;DR: A sum throughput maximization problem for a CR assisted D2D network is modeled considering the RF-EH mechanism and duality theory is used to decompose the problem into multiple sub-problems and Karush-Kuhn-Tucker conditions are exploited to provide the solution of the sub-Problems.

Convex Optimization
Stephen Boyd,Lieven Vandenberghe +1 more
TL;DR: In this article, the focus is on recognizing convex optimization problems and then finding the most appropriate technique for solving them, and a comprehensive introduction to the subject is given. But the focus of this book is not on the optimization problem itself, but on the problem of finding the appropriate technique to solve it.

Cooperative diversity in wireless networks: Efficient protocols and outage behavior
TL;DR: Using distributed antennas, this work develops and analyzes low-complexity cooperative diversity protocols that combat fading induced by multipath propagation in wireless networks and develops performance characterizations in terms of outage events and associated outage probabilities, which measure robustness of the transmissions to fading.

Cooperative strategies and capacity theorems for relay networks
TL;DR: The capacity results generalize broadly, including to multiantenna transmission with Rayleigh fading, single-bounce fading, certain quasi-static fading problems, cases where partial channel knowledge is available at the transmitters, and cases where local user cooperation is permitted.
