Relay stations can be deployed between mobile stations and base stations in a single-hop
wireless network to extend its coverage and improve its capacity. In this paper, we exploit …

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 …

This study considers an orthogonal frequency-division multiple-access (OFDMA)-based
multi-user two-way relay network where multiple mobile stations (MSs) communicate with a …

Abstract<? Pub Inc> The increasing use of relays in wireless communication systems is a
driving force to explore innovative techniques that can improve the quality of service as well …

In this paper, we consider joint resource allocation of a multicell OFDMA-based networks,
with fixed two-hop decode-and-forward relay stations. A joint cell, channel and power …

We investigate the joint problem of power and subcarrier allocation with relay selection for a
multi-user multi-relay cellular system with selective relaying. We first formulate the optimal …

We consider a system with a single base station communicating with multiple users over
orthogonal channels while being assisted by multiple relays. Several recent works have …

In this paper, we study the cooperative strategies of relay stations in wireless relay networks.
In such networks, relay stations distributed across the network and centrally controlled by the …

In cellular networks, users communicate with each other through their respective base
stations (BSs). Conventionally, users are assumed to be in different cells. BSs serve as …

We propose cross-layer optimization frameworks for multihop wireless networks using
cooperative diversity. These frameworks provide solutions to fundamental relaying problems …
