Coexistence of Human-Type Communications (HTCs) and Machine-Type (MTCs) is inevitable. Ultra-Dense Networks (UDNs) will be efficacious in supporting both types communications. In a UDN, massive number low-power low-cost Small Cells (SCs) are deployed with density higher than that the HTC users. such scenario, backhaul capacities constitute an intrinsic bottleneck for system. Hence, we propose m...
