In this paper, cooperative cognitive multiple access schemes with harvesting capability are considered for improving the energy efficiency and spectrum utilization. We consider three scenarios, namely, orthogonal multiple access (OMA), time variable-

In this paper, we consider the downlink of a multiple-input-single-output (MISO) orthogonal frequency division multiple access (OFDMA) based heterogeneous cellular network (HetNet) with multiple legitimate users and eavesdroppers. We assume that the

Consider an orthogonal frequency division multiple access (OFDMA)-based heterogeneous cellular network (HetNet) in which a macrocell is underlaid with several small cells overheard by eavesdropper and jamming by jammer. In this paper, our goal is to

In this paper, we propose a resource allocation algorithm for secure communications in OFDMA relay networks. In our model, a base station wants to securely communicate with a set of users using a set of decode and forward (DF) relay stations (RS) whi

In this paper, we consider a downlink resource allocation in an Orthogonal Frequency Division Multiple Access (OFDMA) based heterogonous cellular network. In order to use spectrum efficiently, we propose Non-Exclusive Spectrum Allocation scheme (NESA
