Although Device-to-device (D2D) communications over licensed wireless spectrum has been recently proposed as a promising technology to meet the capacity crunch of next generation cellular networks, the success, to a large extent, depends on the willingness of the participating devices to share their resources. Consideration of social aspect of human communication can go a long way in extracting efficient solutions to offload cellular traffic. However, due to the high mobility of cellular devices, establishing and ensuring the success of D2D transmission becomes a major challenge. Social aware community based approaches are shown to be useful in identifying a set of reliable relay devices that help a content to be transmitted from a source/cache to a destination.

Objectives:

• Devise novel framework to form multi-hop D2D connections in an effort to maximize time sensitive real-time content delivery
• Design a practical model to predict devise mobility coupled with physical radio network design aspects for transmitting delay-sensitive content
• Devise efficient multicast scheme to leverage similar content request in a particular location for offloading base station traffic
