Energy-Efficient UAV Relaying Robust Resource Allocation in Uncertain Adversarial Networks

Constrained Consumable Resource Allocation in Uncertain Project Networks with Fuzzy Activity Duration

Energy Efficient Techniques for Resource Allocation in Cognitive Networks

The Cognitive Radio paradigm is aimed to optimize the utilization of licensed spectrum bands thanks to coexistence within the same network of licensed (primary) and cognitive (secondary) users. In this context, one of the most important key aspects is represented by an efficient resource allocation between secondary and primary users. Modeling it as an optimization problem, this paper provides ...

Energy-Efficient Resource Allocation in Macrocell-Smallcell Heterogeneous Networks

—Cellular users in indoor environments have difficulty to enjoy high rate services supplied only by macro base station (MBS) due to the penetration loss. Smallcell, as a complement to Macrocell, provide the enhanced coverage through constituting heterogeneous network (HetNet) with MSBs. HetNet is an effective candidate for green communications. However, the interference in HetNet is still a ch...

Energy-Efficient Resource Allocation in NOMA Heterogeneous Networks

Non-orthogonal multiple access (NOMA) has attracted much recent attention owing to its capability for improving the system spectral efficiency in wireless communications. Deploying NOMA in heterogeneous network can satisfy users’ explosive data traffic requirements, and NOMA will likely play an important role in the fifth-generation (5G) mobile communication networks. However, NOMA brings new t...

Low Complex Energy-Efficient Resource Allocation in Femtocell Networks

Femtocells have attracted growing attention in academia, industry, and standardization forums in recent years. However, most of existing works on femtocell networks are focused on spectrum efficiency and interference mitigation, energy efficiency aspect is neglected. In this paper, we investigate the energy efficient resource allocation of downlink femtocell networks in sparsely and densely dep...
