Abstract

The ultra-high bandwidth available at millimeter (mmWave) and Terahertz (THz) frequencies can effectively realize short-range wireless access links in small cells enabling potential uses such as driver-less cars, ultra-high-definition infotainment services and data backhauling. In this context, in alternative to fiber-based and legacy wireless-based backhauling, vehicles can be used as digital mules to increase the data throughput of a region served by a software defined network (SDN) transmitting data to the Software Defined Base Station (SD-BS), equipped with only one mmWave/THz transceiver. In real applications, multiple vehicles may concurrently pass through the region and related data throughput depends on the relative distance with respect to the transceiver. For technological reasons, the SD-BS transceiver can be used by just one vehicle at each time instant (time-slot). Hence, an operational decision problem arises consisting in determining the assignment of the vehicles to the time-slots of the SD-BS maximizing the data throughput. The problem can be conceived as a variant of different combinatorial optimization problems like scheduling and assignment problems. An original mixed integer linear programming formulation of the problem is presented and tested on real-like instances generated from a case study.
