Evolved Multimedia Broadcasting and Multicasting Services in LTE-A Using Device to Device Communication

With the rapid growth in data services including multimedia downloading, video conferencing, live streaming and mobile TV in the last few years, there has been increased demand of LTE broadcasting. However, there are many challenges in this area and one of the biggest problems occurs when several users subscribe to the same multimedia service. Then it becomes inefficient to transmit the same content multiple times to subscribers via unicast. This problem is aggravated when the number of users coming in between the multicast session is huge. In order to overcome this, dynamic scenario is proposed that incorporates Device-to-Device (D2D) communication along with Multimedia Broadcasting and Multicasting Services of LTE. This is achieved by integrating multicasting and D2D communication between the users. The performance of static as well as dynamic scenario is compared on various metrics. In addition to this, performance of various device discovery protocols supporting this model has been analyzed and compared with static scenario.
