Survey and analysis of power control for collaborative networks

The aim of this paper is to first review power allocation solutions for wireless relay networks and show how channel state information (CSI) availability and system diversity are the dominant factors, as opposed to relaying protocols: i.e., amplify or decode and forward. We then introduce power allocation solutions for a cooperative network, where users act as relays for each other, and utilize powerful coding schemes. In the analysis, we compare cooperative solutions to the relaying solutions.
