Modeling D2D communications with LTE and WiFi [PDF]
ACM SIGMETRICS Performance Evaluation Review, 2014 In this work we propose a roadmap towards the analytical understanding of Device-to-Device (D2D) communications in LTE-A networks. Various D2D solutions have been proposed, which include inband and outband D2D transmission modes, each of which exhibits different pros and cons in terms of complexity, interference, and spectral efficiency achieved. We go
