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 ...
متن کاملStochastic Resource Allocation for Energy-Constrained Systems
Battery-powered wireless systems running media applications have tight constraints on energy, CPU, and network capacity, and therefore require the careful allocation of these limited resources to maximize the system’s performance while avoiding resource overruns. Usually, resource-allocation problems are solved using standard knapsack-solving techniques. However, when allocating conservable res...
متن کاملAn Energy-efficient Mathematical Model for the Resource-constrained Project Scheduling Problem: An Evolutionary Algorithm
In this paper, we propose an energy-efficient mathematical model for the resource-constrained project scheduling problem to optimize makespan and consumption of energy, simultaneously. In the proposed model, resources are speed-scaling machines. The problem is NP-hard in the strong sense. Therefore, a multi-objective fruit fly optimization algorithm (MOFOA) is developed. The MOFOA uses the VIKO...
متن کاملResource allocation for energy efficient cellular systems
The need for more throughput in wireless cellular networks has been increasing in recent years. It has led to an increase in operational costs due to higher energy use as operators deploy more cell sites or increase transmission power at existing ones to satisfy demand. Energy costs are a major expense, and reducing them is a priority. This article presents a scheduler which aims to solve the p...
متن کاملResource allocation for OFDM-based multiuser cooperative underlay cognitive systems
This paper investigates the resource allocation problem for a multiuser underlay cognitive system where the secondary system is allowed to transmit and cooperate with the primary system. In this scenario, the secondary users are subject to two main constraints in the presence of the primary user: their total power budget and the allowable interference threshold at the primary receiver. Power an...
