Cost-oriented virtual resource allocation for device-to-device communications underlaying LTE networks
Yulun Cheng, Longxiang Yang · 2017
Wireless virtualization is an emerging solution for future wireless networks. Besides, device-to-device (D2D) communications has also gathered significant attention as another promising technology to meet the increasing demand. To merge the merits of the both, this paper addresses the virtual resource allocation with D2D communications underlaying LTE networks. By considering the cost of all the service providers (SP), the problem is formulated as a binary integer programming. On the basis of that, the cost-oriented virtual resource allocation is proposed. Simulation results shows that the proposed scheme outperforms the benchmark in terms of the total utility and cost for all the SPs.
