Research on Multi-protocol Access Method for IoT Platform Based on Microservice Container Scheduling

The number of Internet of Things (IoT) devices in the world has grown to 43 billion in 2023. With the expansion of the IoT industry, the types and communication protocols of IoT devices are also increasing. In the actual deployment of the Internet of Things, it is more complicated and difficult to develop a truly interconnected IoT platform in the face of a variety of IoT devices. At the same time, the increasing number of devices has brought great challenges to the high availability of the platform. We designed and implemented a multi-protocol access method for the IoT platform, which can configure public and private protocols according to requirements, and make up for the shortcomings of the current IoT platform in device access. In order to ensure the availability of the platform, the container dynamic scheduling method is generally adopted when the sudden high load demand is needed. However, due to the time-consuming operation in the container scaling process, the existing container scheduling method cannot immediately meet the load demand. We proposed a combined prediction model based on LSTM and RELM, and proposed a container dynamic scheduling strategy based on load prediction. This scheduling strategy is applied to the multi-protocol access method to ensure the stability and availability of the access process. Finally, the multi-protocol access method is tested. The results show that this method can ensure the access of multi-protocol IoT devices. The reliability test shows that it has good performance and meets the current demand for IoT platforms. In addition, the strategy of this paper is compared with other strategies to further verify the rationality and availability of the method.
