Energy-Efficient Subcarrier Pairing and Power Allocation for DF Relay Networks with an Eavesdropper
Algorithms for joint subcarrier pairing and power allocation are investigated in order to maximize the worst-case energy efficiency (EE) in dual-hop decode-and-forward (DF) relay networks in the presence of an active eavesdropper. Accordingly, we study the impact of number of subcarriers on the trade-off in performance between the EE and the spectrum efficiency (SE). The formulated EE optimizat...
متن کاملJoint power, subcarrier and subframe allocation in Multihop relay networks
In this paper we study the problem of subframe, subchannel and power allocation in OFDMA-based multihop relay networks. The system consists of a base station (BS), a number of relay stations (RS) and mobile stations (MS). We consider frame by frame scheduling, where the frame is divided into two subframes such as BS-RS and RSMS subframes. We study two different problems, satisfying link rate re...
متن کاملOutage Probability and Power Allocation for Two-Way DF Relay Networks with Relay Selection
In this paper, we investigate the outage probability and power allocation for the two-way decode-andforward (DF) relay networks with relay selection. Specially, we consider independent but not necessarily identical distributed Rayleigh fading channels. Firstly, we derive an exact closed form outage probability expression. To shed light on the relation between the outage probability and the powe...
متن کاملEnergy Efficient and Subcarrier Allocation for OFDMA based Cooperative Relay Networks
Energy efficient wireless communication is important for battery constrained mobile devices. For mobile devices in a cellular system, uplink power consumption dominates the wireless power budget because of RF power requirements for reliable transmission over long distances. In this work we developed a low-complexity subcarrier-power allocation and relay selection scheme has been developed for m...
متن کاملEnergy-Efficient Power Allocation Strategy in Cognitive Relay Networks
Cognitive radio and cooperative technique are two essential techniques for the future generation green communication paradigm owing to its inherent advantages of adaptability and cognition. Typically, previous studies on power allocation in the cognitive relay networks often concentrate on two goals independently: the first goal is to minimize the transmit power to reduce energy consumption, as...
