Journal ArticleDOI
Instantly decodable network coding for real-time device-to-device communications
TL;DR: The paper shows that, under particular scenarios, the problem boils down to a maximum clique problem and presents a fast selection algorithm, which provides appreciable complexity gain as compared to the optimal selection one, with a negligible degradation in performance.
Journal ArticleDOI
Cost-effective hybrid RF/FSO backhaul solution for next generation wireless systems
TL;DR: A cost-effective hybrid RF/free-space optical (FSO) solution to combine the advantages of RF backhauls (low cost, NLOS applications) and FSO backhauling (high-rate, low latency) is proposed.
Journal ArticleDOI
Resource allocation in heterogeneous cloud radio access networks: advances and challenges
TL;DR: Simulations results show how the proposed strategies provide appreciable performance improvement compared to methods from recent literature: coordinated scheduling, hybrid backhauling, and multicloud association.
Journal ArticleDOI
Hybrid Radio/Free-Space Optical Design for Next Generation Backhaul Systems
TL;DR: In this article, a hybrid RF/FSO backhaul solution is proposed to minimize the cost of the backhaul network by choosing either OF or hybrid RF-FSO links between the base stations, so as to satisfy data rate, connectivity, and reliability constraints.

Hybrid Radio/Free-Space Optical Design for Next Generation Backhaul Systems
TL;DR: Simulation results show that the proposed solution shows a close-to-optimal performance, especially for reasonable prices of the hybrid RF/FSO links, and reveal that the hybrids are a cost-efficient solution and a good candidate for upgrading the existing backhaul networks.
