Realize Smart City Applications with LoRaWAN Network

Internet of Things is an important part of realizing smart cities, this article introduces a proposal to build an Internet of Things system with LoRaWAN to achieve diverse smart city applications. There are three problems proposed and resolved in this research, how to maximize wireless devices’ lifetime with LoRa protocol characters， how to choose the gateways’ location for improving the efficiency and reduce costs, and about a good way to set up network servers to balance performance and consumption to implement in smart city applications. The IoT platform is built completely and running three applications on it in this research, Smart Parking, Smart Building Monitoring and Smart Sewage Monitoring. The methods of build platform and set applications are also explained in this article
