We consider designing a distributed scheduling algorithm for multi-homing users in heterogeneous cache-enabled small cell networks. The aim is to minimize the total operation cost on condition that all users' QoS requirements are satisfied. The proposed algorithm is based on alternating direction method of multipliers (ADMM) and can be carried out in each small cell base station (SCBS) independently. Simulation results show that the operation cost converges to the global optimum after a few iterations and the proposed algorithm outperforms a conventional distributed method largely.
