A novel spectrum allocation scheme for software-defined LTE-WiFi network
Muntadher Alshaikh Ali, Abbas Jamalipour · 2018
In this article we propose a harmonious licensed-unlicensed spectrum management framework for LTE and WiFi coexisting in a software defined environment. Two key resource dimensions are employed, bandwidth and Virtual Queues (VQs), in conjunction with a third resource dimension, i.e. time. The full potential of this novel approach lies in the replacement of inter-technology carrier sensing with centrally managed resource access via leveraging the global view of Software Defined Networking (SDN). Results illustrate that the proposed paradigm addresses together selectivity and fairness for LTE and WiFi, as well as demands for both high and low priority traffic. The outcomes also show holistic superiority for our framework when compared with two other benchmark schemes.
