LoRaWAN is one of the most promising standards for IoT technology. However, the expected number of huge traffic and applications run over the IoT system puts high constraints on the system design. To this end, this paper proposes a reliable LoRaWAN system for ultra-dense IoT networks. The system employs to recent technologies to enable the ultra-low latency applications besides managing massive traffic results from the expected deployed devices. The first system deploys mobile edge computing to provide the computing and energy resources at the edge of the access network, while the second part deploys the software defined networking (SDN) at the core network to manage and control the whole network traffic. The novelty of the proposed system comes from the deploying of a distributed version of the SDN controller at the edge servers, to reduce the load on the core network. The system is simulated for various simulation scenarios and the results validate the proposed structure for ultra-dense and ultra-low latency IoT networks.

Keywords:LoRaWAN, MEC, SDN, Latency, Dense deployment
