This paper considers a general energy harvesting cooperative network with M source-destination (SD) pairs and one relay, where the relay schedules only m user pairs for transmissions. For the special case of m = 1, the addressed scheduling problem is equivalent to relay selection for the scenario with one SD pair and M relays. In conventional cooperative networks, the max-min selection criterio...

Relay technologies have the potential to offer extended cell coverage and improved capacity over the Next Generation Wireless Broadband Radio Access Networks. Standards development organizations are considering how to incorporate relay technologies into new standards. This article provides an overview of the relay-based technology concepts for two of the most promising next generation wireless ...

This paper investigates a communication method using unequal loss protected layered video and explores use of this over a cooperative relay network. The method is adapted to prioritized video transmission to explore two prioritized layering (scalable) video techniques. Cooperative communication networks can reduce power consumption and benefit wireless networks, where intermediate nodes act as ...

Submitted: May 9, 2013; Accepted: Jun 16, 2013; Published: Jun 30, 2013 Abstract: In this paper, we consider a dual-hop Cognitive Radio Networkthat consists of a secondary sourcedestination pair assisted by cognitive relays in their communication. The whole network is operating in an underlay mode near a primary user. Underlay networks allow simultaneous primary and secondary transmissions but ...

With the fast development of communication networks, cooperative communication has been more widely used in many different fields, such as satellite networks, broadcast networks, internet and so on. Therefore relay channels have been playing a pivotal role since their definitions were proposed by Van-der Meulen. However, the general achievable rate region of a relay channel is still unknown whi...
