Abstract:
In the present day, 5G and beyond networks are being designed to support the future
increase of data tra_c 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 tra_c 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 di_erent 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 e_ciency
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 e_ciency. 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
