Souvik Deb, Shankar K. Ghosh, Avirup Das, Sridevi S, Jacob Augustine, Rajib Mall

TL;DR
This paper introduces an AHP-based mode selection algorithm for D2D-enabled NSA 5G networks that considers user service requirements and mobility, improving key performance indicators across multiple service slices.
Contribution
It proposes a novel two-level AHP mechanism for mode selection that incorporates service needs and mobility effects, reducing unnecessary handovers in D2D-enabled NSA 5G networks.
Findings
Outperforms existing methods in key performance indicators for all three slices.
Effectively considers user service requirements in mode selection.
Reduces handover frequency by accounting for UE mobility.
Abstract
Device-to-device (D2D) communication was proposed to enhance the coverage of cellular base stations. In a D2D enabled non-standalone fifth generation cellular network (NSA), service demand of a user equipment (UE) may be served in four \emph{modes}: through LTE only, through NR only, through LTE via D2D and through NR via D2D. Such mode selection should consider the service requirements of the UEs (e.g., high data rate, low latency, ultra-reliability, etc.) and the overhead incurred by handovers. In existing mode selection approaches for D2D enabled NSA, the service requirements of the UEs have been largely ignored. To address this, in this paper, we propose a mode selection algorithm for D2D enabled NSA based on a two-level Analytic Hierarchy Process (AHP). The proposed AHP-based mechanism considers the service requirements of the UEs in level 1; and mode selection options (i.e., LTE…
