The frequency allocation problem is to assign frequencies to the users so that signal interference is avoided, minimizing the total number of frequencies used. Such a problem is called a distributed constraint optimization problem (DCOP), and the asynchronous distributed optimization algorithm has been proposed as an exact method for DCOP that can find the optimal solution asynchronously. However, this algorithm is insufficient in the case that the same frequency locally concentrates on one area because the communication bandwidth may not be effectively used. In this study, we propose the algorithm for distributing the constraint violation to the whole by considering the local load making the best use of the feature of the asynchronous distributed optimization algorithm. Moreover, this algorithm is evaluated, and considered by the simulation experiment. |
