IEEE Access Special Section: Advances in Interference Mitigation Techniques for Device-to-Device Communications

Abstract

The emergence of data-extensive applications such as online gaming and video sharing has resulted in an exponential increase in mobile data traffic. Advances in the Internet-of-Things (IoT) and 5G also require the fusion of multiple sensors and wireless devices operating in real time. Supporting such high data rate demands within the framework of existing wireless access networks is a challenging task. Addressing this ever-increasing demand of data-hungry devices in an efficient and effective manner has driven the wireless industry to look into new paradigms. Device-to-Device (D2D) and Machine-to-Machine (M2M) communications are viewed as promising solutions to this complex problem and hence a key enabling technology for 5G and IoT applications. The D2D is envisioned to operate either in out-band mode, representing use of a dedicated spectrum, or in-band mode, representing operation within the same spectrum of the existing cellular spectrum. Variations of Vehicle-to-Vehicle (V2V) and Human-to-Human (H2H) are used to deal with the specific nature and application of the wireless network under consideration.
