Mobile Data Offloading under Attractor Selection in Heterogeneous Networks

To offload the increase of the mobile data traffic, the heterogeneous network offloading is regarded as one of the most promising techniques to reduce the workload on the existing cellular network. A novel heterogeneous network system, which integrates the power line carrier (PLC) network and the cellular network, is proposed. The proposed system employs the PLC network instead of the traditional WiFi network to offload the mobile data. Then, the throughput of the PLC network and the cellular network are calculated. Moreover, We formulate the mobile data offloading problem as a maximization problem of the throughout in the PLC network. Therefore, the attractor selection algorithm is employed to obtain the maximization throughput of the proposed system. Finally, the numerical results show that the proposed system providing the better throughput and stability, compared with the On-the-spot offloading and the WiFi offloading system.
