A kind of novel method of power allocation with limited cross-tier interference for cognitive
radio network (CRN) is proposed in this paper. In this method, an interference-limited power …

We consider secure resource allocations for orthogonal frequency division multiple access
(OFDMA) two-way relay wireless sensor networks (WSNs). The joint problem of subcarrier …

Smart grid with latest technologies provides solid foundation for the implementation of
energy management systems at home premises. This paper proposes an autonomous …

In this paper, we investigate the resource allocation problem in a single-user relay-aided
cognitive radio (CR) underlay network. Both the CR network and the primary network …

The rapid growth of energy consumption due to the strong demands of wireless multimedia
services, has become a major concern from the environmental perspective. In this paper, we …

In this paper, a novel resource allocation algorithm is investigated to maximize the energy
efficiency (EE) in multiuser decode-and-forward (DF) relay interference networks. The EE …

In this paper, we consider a multi-user single-relay wireless network, where the relay
facilitates transmissions of the users' signals to the destination. We study the relay power …

In this paper, we study the problem of energy-efficient resource allocation in multiuser two-
way amplify-and-forward (AF) relay networks with the aim of maximizing the energy …

In this letter, we study a classic three-node relay network with two end nodes and one relay.
A unified signal model is proposed to represent four typical relay modes, namely, one-way …

Joint resource allocation involving optimization of subcarrier allocation, subcarrier pairing
(SCP), and power allocation in a cooperative secure orthogonal frequency division multiple …
