On Radio Resource Allocation in Proactive Cooperative Relaying

Cooperative relaying has drawn great interest to mitigate the negative effects of small-scale fading in distributed wireless networks. This paper analyzes radio resource allocation in cooperative relaying with proactive relay selection. Due to the introduction of the relay into the communication link an over-expenditure of resources can take place similar to the classical exposed terminal problem. In this work we derive the overall network throughput in two simple scenarios and determine the regions of packet-error-rates where cooperative relaying yields a throughput gain.
