Distributed Power Allocation Algorithm for Amplify-and-Forward Relaying Networks

In relaying networks, distributed resource allocation algorithms are preferable than the centralized ones due to implementation concerns. Using dual decomposition, we proposed a Distributed Power Allocation Algorithm (DPAA) for relaying net-works that employ Amplify-and-relaying (AF) protocol. Simulation results show the convergence of the algorithm with insignificant performance loss compared to the Centralized Power Allocation Algorithm (CPAA).
