Context-Aware Mode Selection for 5G Multi-Hop Cellular Networks

Abstract

In the present day, 5G and beyond networks are being designed to support the future increase of data traffic and service demands. To support such increase, 5G networks will incorporate device-centric technologies with adequate mechanisms to scale and handle the growing and very large number of connected devices and traffic demands. Device-centric technologies include Device-to-Device (D2D) communications and Multi-hop Cellular Networks (MCNs). In device-centric wireless networks, devices will be able to connect to the network using two different connection modes: through a traditional cellular connection, or through a multi-hop cellular connection based on D2D communications with intermediate mobile devices. Device-centric technologies will therefore provide new connectivity options and significant opportunities to enhance the capacity and efficiency of 5G networks. However, new challenges will need to be addressed. One of them is the selection of the most adequate connection mode for each mobile device, because it will be key to improve the network performance and efficiency. This work proposes a context-aware mode selection scheme capable of identifying and selecting the most adequate connection mode for each device under a wide range of deployment and operating conditions. The proposed scheme estimates the benefits and risks of each connection mode based on context information available at the base station guaranteeing low signaling overhead. The obtained results show that the proposed mode selection scheme helps achieving throughput gains higher than 200% compared to traditional single-hop cellular communications for devices at the cell edge, and significant gains are also achieved compared to other mode selection schemes implemented and evaluated.

“…In [181], the authors investigate the mode selection problem for D2D communication and multi-hop cellular communication underlaying HetNets in the downlink scenario. They provide a context-aware mode selection method to determine each device's optimal communication mode.…”

“…The techniques, advantages, and limitations of the current research are highlighted. Furthermore, the recent works are classified based on the performance metrics of the mode selection that have been considered such as energy efficient [170], [171], [172], [173], [174], [175], spectrum efficient [176], [177], [178], and distance based [179], [180], [181] as shown in fig. 10.…”
