Integration of LoRaWAN and 4G/5G for the Industrial IoT
- Current forecasts predict that the Industrial Internet of Things will account for about 10 billion devices by 2020. Simultaneously, unlicensed low-power wide area networks are gaining momentum due to their low cost, low power, and long range characteristics, which are suitable for many IIoT applications, in addition to the usage of unlicensed bands.
- In this article, a solution is proposed to seamlessly integrate LoRaWAN, an open and standardized LPWAN technology, with 4G/5G mobile networks, thus allowing mobile network operators to reutilize their current infrastructures. This proposal is transparent to LoRaWAN end devices and to the EPC, since only the LoRaWAN gateway needs to be modified.
- The gateway acts as an evolved Node B from the core network perspective, implementing part of the eNB protocol stack. All data packets transported over the core network are both encrypted and integrity protected, hence achieving end-toend security. As a proof of concept, this solution has been implemented and validated with an open source EPC.
LPWANIEEE 802.11ah and LoRaWAN capacity simulation analysis comparison using NS-3
- Low Power Wide Area Networks are the fundamental keys of the internet of Things (IoT). These networks provide long-range coverage to end nodes, exploiting license-free frequency bands and the sub 1Ghz communications.
- In this paper we evaluate and analyze using NS-3 network simulator, the uplink throughput of the two promises networks IEEE 802.11ah and LoRaWAN all by implementing the maximum number of the end devices served by a single base station.
- Also in the second scenario where the nodes are depends on the distance from the base station. In the conclusion we brief and compare the obtained results, and we make actions to be taken in case of making applications or deployments using these networks.
