A relaying can significantly improve performance of contemporary mobile networks in terms
of capacity and/or energy consumption. Nevertheless, an incorporation of conventional relay …

Abstract Device-to-device (D2D) communication was originally presented as an efficient
solution to boost conventional cellular network performance. Since the signals degrade …

With the gradual promotion of the fifth generation (5G) mobile communication and Internet of
Things (IoT) applications, wireless communication transmission will be more vulnerable to …

Combining energy harvesting (EH) and device-to-device (D2D) communication underlaying
5G cellular networks is a very promising direction to improve both energy and spectral …
