摘要：
This paper studies the resource allocation for orthogonal frequency-division multiple-access relay network with multiple source nodes, multiple relay nodes, and a single destination node. The optimal source/relay/subcarrier allocation problem with fairness constraint on relay nodes is formulated as a binary integer programming problem. The problem is then tackled using a graph theoretical approach by transforming it into a linear optimal distribution problem in a directed graph. Upper bound of the solution is discussed and simulation results are studied to evaluate the algorithm performance.
