A Converged Network Architecture Oriented Towards NB-IoT

Abstract

Although NB-IoT’s standardization gives us a future direction, we have to face some issues of existing networks converged, especially, the wireless sensor net-work (WSN) and cellular networks (CN) converged. On the other hand, the increase in number of sensor nodes and in the mobile devices is forcing the backhaul network architecture to undergo radical transformation. To meet the requirements of low latency and high quality of service (QoS), we put forward a novel converged network architecture. Meanwhile, we give three application scenarios. The analysis results show this architecture could facility the network design.
