PROJECT TITLE :

DORE: An Experimental Framework to Enable Outband D2D Relay in Cellular Networks - 2017

ABSTRACT:

Device-to-Device (D2D) communications represent a paradigm shift in cellular networks. In explicit, analytical results on D2D performance for offloading and relay are very promising, but no experimental proof validates these results to this point. This paper is the primary to provide an experimental analysis of outband D2D relay schemes. Moreover, we design D2D opportunistic relay with QoS enforcement (DORE), a complete framework for handling channel opportunities offered by outband D2D relay nodes. DORE consists of resource allocation optimization tools and protocols appropriate to integrate QoS-aware opportunistic D2D communications among the architecture of 3GPP Proximity-based Services. We implement DORE using an SDR framework to profile cellular network dynamics within the presence of opportunistic outband D2D communication schemes. Our experiments reveal that outband D2D communications are suitable for relaying in a very massive variety of delay-sensitive cellular applications, and that DORE enables notable gains even with a few active D2D relay nodes.
