[edit] Abstract

The deployment of fixed relays will improve communication in wireless networks. Suitably located wireless relays facilitate communication between a source-destination node pair by receiving the source transmission and forwarding it to the destination. In a reasonably dense network, several relays may be available to assist a particular source-destination pair. Deciding which wireless relays should forward the source transmission is not straightforward, though. In particular, relay selection involves resolving tradeoffs between different layers of the OSI protocol stack, including the MAC and physical layers. This article provides an overview of the relay selection problem. We describe two types of strategies for addressing this problem, namely centralized and decentralized approaches, and present both prior work and our contributions for both types of strategies. Our contributions are both highly intuitive and illustrate the importance of system-specific design.
