Multi-Path approach for real-time service delivery optimization over HetNets

With the new era of smartphones, the access devices have many radio interfaces like WiFi/3G/4G. Those interfaces can work in concurrent mode in order to improve the overall network access. Meanwhile, they could enhance the service continuity and maximize the application throughput through providing uninterrupted service supply. In this paper, we introduce a Multi-Path (MP) approach using TCP over different radio interfaces for real time applications delivery. Then, a hybrid way combines MP-TCP with DASH technology is proposed as amelioration for video service delivery optimization over Internet. Our test indicates an improvement in handover delay comparing to single path TCP. Moreover, the MP-TCP with DASH enhances the quality of video transmission by rates of different radio interfaces available.
