Social aware information dissemination for device to device communication

Abstract

Due to ever increasing demanding for higher data rates, a lot of work is being done on 5G. Device to Device (D2D) communication, a paradigm of 5G, is a technology in which devices can communicate directly with each other bypassing the Base Station (BS). D2D is an efficient scheme to improve spectral efficiency, energy efficiency, offload data from BS and to increase network capacity. However there are many challenges associated with this vital technology including efficient resource allocation and interference management. Particularly, in underlay communication, where cellular and D2D users share the same spectrum, it becomes critical to devise a technique in order to ensure efficient radio resource utilization while catering interference issues. Recent works have been focusing on physical domain constraints however our aim is to utilize the social human behaviors to resolve the D2D resource allocation problems. This thesis proposes a framework for effective resource allocation by leveraging social networks and forming social communities. The suggested technique is likely to improve the D2D rate and coverage probability at the same time. Numerical simulations are also illustrated to show the effectiveness of our proposed scheme as compared to the existing ones. Some applications of D2D are: • Public safety services • Content sharing/ local multicasting • E-health
