Centralized and Distributed Power Allocation in Multi-User Wireless Relay Networks
Abstract—Optimal power allocation for multi-user amplifyand-forward wireless relay networks in which multiple sourcedestination pairs are assisted by a set of relays is investigated.1 Two relay power allocation strategies based on maximization of either i) the minimum rate among all users or ii) the weighted sum of rates are developed. A distributed implementation of the maximum weighted-sum-rate power allocation strategy is also studied. Numerical results demonstrate the efficiency of the proposed strategies and reveal their interesting throughputfairness tradeoff in resource allocation.
