The Relay Selection and Transmission Trade-Off in Cooperative Communication Systems

Executive Summary

A common and practical paradigm in cooperative communication systems is the use of a dynamically selected best relay to decode and forward information from a source to a destination. Such systems use two phases a relay selection phase, in which the system uses transmission time and energy to select the best relay, and a data transmission phase, in which it uses the spatial diversity benefits of selection to transmit data. In this paper, the authors derive closed-form expressions for the overall throughput and energy consumption, and study the time and energy trade-off between the selection and data transmission phases.
