Wi-Fi enabled Device-to-Device communication in underlying cellular networks

Device-to-Device communication underlaying cellular networks will become breakthrough innovation in future cellular networks such as LTE and LTE Advanced. Device-to-Device communication allows devices to communicate with each other without using the cellular infrastructure and reduces the load on the network. This can be achieved by using several approaches, one of them being use of built in Wi-Fi, we have developed such an application which is highlighted here. The application is implemented in real time to exchange information between devices. This paper also focuses on the research on the concepts of direct device communication along with the possible scenarios the devices can communicate. Finally the paper concludes by presenting the results and discusses the future enhancements.
