We propose a robust resource allocation framework to improve the physical layer security in
the presence of an active eavesdropper. In the considered system, we assume that both …

In this paper, we develop and analyze three limited-feedback resource allocation algorithms
suitable for uplink transmission in heterogeneous wireless networks (HetNets). In this setup …

The ergodic resource allocation (ERA) problem for uplink transmission in underlay cognitive
radio networks (CRNs) is investigated. The objective is to maximize the ergodic sum-rate of …

In this paper, we propose a limited rate feedback scheme for decode-and-forward (DF) relay-
assisted networks. It is assumed that the cellular user is far from the base station such that …

In this paper, we propose a device-to-device (D2D) communication scenario underlaying a
cellular network, where both D2D and cellular users (CUs) are discrete power-rate systems …

A joint resource allocation policy for an underlay multi-user secure cognitive radio network
(CRN) adopting the time-division multiple-access scheme with the guarantee of the …

In this paper, we consider the problem of resource allocation for secure communications in
decode-and-forward (DF) relay-assisted orthogonal frequency-division multiple access …

Proportional fair resource allocation plays a critical role to enhance the performance of slow
adaptive orthogonal frequency division multiple access (OFDMA) system. In slow adaptive …

A robust Ergodic Resource Allocation (ERA) scheme is proposed in this paper in the
framework of an orthogonal frequency division multiple access (OFDMA) based underlay …

This paper studies the required physical (eg relays and jammers) and radio resources (eg
power) to provide physical layer security for relay and friendly jammer assisted multiple …
