 Obiettivo del progetto (Objective)

'The wireless channel has a broadcast nature. Therefore, transmissions intended for one destination are also overheard by other nodes. These undesired signals create interference which makes it harder for the nodes to decode their information. Current network design is focused on suppressing interference, turning the network into a virtual collection of point-to-point links. As a result, the performance of current wireless networks is largely determined by the point-to-point links' performance. The increasing demand for high-speed reliable communication has motivated the consideration of network strategies beyond the point-to-point approach, thereby focusing the attention on cooperative strategies. Here, instead of suppressing interference, the fact that interference contains information relevant to other nodes is exploited to enhance the performance of the network. Cooperative strategies are expected to improve the rates, reliability and energy-efficiency in networks. This proposal focuses on the fundamental aspects of cooperation. The three main cooperation types - relaying, conferencing and feedback, will be studied. Relaying strategies that aim at increasing the interference at interfered nodes will be considered. This is in complete contrast to the prevailing practices which are based on forwarding desired information to its intended destination. Feedback schemes in which the feedback originates from nodes in the vicinity of the destination receiver will be considered. Finally, conferencing - a cooperation scheme in which receivers interactively help each other to decode, shall be investigated. The focus will be on developing conferencing schemes for channels with memory. Cooperation strategies are currently being considered for new wireless standards. Hence, the proposed research is well-timed for affecting the design of future wireless networks. This research will have a substantial impact on both theory and practice of node cooperation in wireless networks.'

Introduzione (Teaser)

Researchers are exploring the potential of a cooperative strategy approach to inform the future design of wireless communication networks.

Descrizione progetto (Article)

As demand for high-speed reliable communication increases, network design is moving beyond the point-to-point approach that sought to minimise interference of transmitted information over wireless channels. With the latter being reliant on the performance of point-to-point links, attention is turning to cooperative strategies that actually aim to exploit rather than suppress interference.

The 'Cooperation strategies in wireless networks: Relaying, feedback and conferencing' (RFC) project is investigating the benefits of employing such a novel approach, and promises improved rates, reliability and energy efficiency in networks. Focusing on relaying, feedback and conferencing as the broad categories of such strategy, the EU-funded research team has already made significant discoveries with positive implications for the future design of wireless networks.

Work on the so-called multiple-access channel with multiple relays (MACMR) indicated the potential for considerable performance improvement by letting relays interact with each other. Other study investigations have pointed to a strong motivation for incorporating relaying and feedback, deemed the most important cooperation types, into wireless networks.

RFC project results are also making headway in the characterisation of sufficient and necessary conditions for reliable communication. Study outcomes have the potential to raise the bar on new wireless standards and optimal network design for enhanced communication.
