Abstract
With the development of Internet of Thing (IoT) technologies, more and more intelligent devices can detect many kinds of environmental conditions, and send collected data or alarm back to application system automatically. If those massive IoT devices are connected via LTE network and the system need to send instructions to those IoT devices, the amount of data transmission in LTE would be raised quickly. To reduce the transmission load, multicasting provided by LTE evolved Multimedia Broadcast Multicast Services (eMBMS) service is one of solutions. However, the eMBMS service is dominated by the device with lowest signaling quality resulting in poor efficiency. A Device-to-Device (D2D) based mechanism was proposed to improve transmission efficiency of eMBMS service in this paper. Simulation results have shown that the proposed D2D-based mechanism can reduce the number of allocated resource blocks.
