Secure and Smart Media Sharing Based on Direct Communications among Mobile Devices Underlying in Lte-a Cellular Network

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? To date, there are many papers available on D2D communications in cellular networks. But, there is no paper on proposing security measures and business models for D2D communications in cellular networks. We propose a secure and smart solution that answers the three challenges thereby enhancing efficiency of D2D communications in a smart and secure manner. Our solution will demonstrate that the proposed application level security framework will output reduced network congestion, better pricing schemes, auctioning system and less or no security threats than the current legacy non-D2D communication models.
