For the prominent superiorities in energy and spectrum efficiency, Device-to-Device (D2D)
communication has become a hot topic among the 5th generation (5G) technologies …

We consider the problem of joint mode selection and resource allocation for D2D and
femtocell users in a three-tier dense heterogeneous network in which all the users can reuse …

In this paper, a new mode selection (MS) scheme for device-to-device (D2D) enabled
cellular networks is proposed. The MS is carried out using a predefined signal-to …

Recent events of multiple earthquakes in Nepal, Italy and New Zealand resulting loss of life
and resources bring our attention to the ever growing significance of disaster management …

One of the major challenges to the performance of device-to-device (D2D) communications
co-existing with cellular links lies in the interference management. Mode selection has been …

Device-to-device (D2D) communications offload the data traffic from the cellular network and
improve spectral and energy efficiency. Non-orthogonal multiple access (NOMA) is an …

In recent decades, serious natural disasters such as earthquakes, floods, tsunamis, and
forest fire have occurred with catastrophic consequences. To minimize the loss of lives and …

More than half of the world population lives in cities, and the trend of moving to bigger cities
is increasing with the time (Chourabi et al., 2012). This increase in population of the cities is …

In this paper, we consider a heterogeneous network consisting of both macro Base Station
(MBS) and pico Base Stations (PBSs) in order to provide a spectrum allocation and mode …

Device to device (D2D) communication that provides high data rate proximity based direct
communication between users, along with simultaneous wireless information and power …
