Abstract
Cellular network service providers are trying to expand their capacity to accommodate the increasing mobile traffic demand by adopting new mobile technologies like user proximity based Device-to-Device (D2D) communication underlying existing Long Term Evolution-Advanced (LTE-A) cellular network, which is a promising technology to overcome legacy cellular network's congestion. D2D communication is a new paradigm to enhance legacy LTE-A cellular network performance. However, there are several challenges to be overcome: 1) what will be the trending technology for overcoming cellular network data traffic congestion? 2) How can we overcome security threats and high pricing for data services? And 3) how can users earn revenue by media sharing? We propose a secure and smart D2D communication framework that answers the three challenges thereby enhancing efficiency of D2D communications in a smart and secure manner. Our framework demonstrates that the proposed application level security and procedures provide reduced network congestion, better pricing schemes, and less or no security threats than the current legacy non-D2D communication model.
