Cross-layer approach enabling communication of high number of devices in 5G mobile networks

Introduction of Internet of Things and Machine Type Communication to future mobile networks will cause significant increase in the number of connected devices. At the same time, the connected devices can change traffic patterns as frequent transmission of small volumes of data is expected from sensors and machines. Transmission of such data is very inefficient due to redundancy of signaling information. In this paper, we analyze limits for the number of devices and machines communicating in current 4G mobile network. Then, we propose a novel solution, which shifts the current limits of the number of communicating devices towards requirements on 5G mobile networks. The proposed solution exploits cross-layer approach considering buffering of data and clustering of nearby users in order to minimize overhead and improve transmission efficiency. This way, we can increase the number of devices served by a single cell up to 24 times comparing to the state of the art solution.
