Internet of Things System Based on Mobile Communication Network

摘要

To successfully establish a unified and standardized Internet of Things (IoT) system, a specific scheme based on the bandwidth and quality of service (QoS) analysis as well as the third generation mobile communication system is given. The basic architecture of the IoT is introduced, the technical requirements of each level on the network are put forward, and the application of the IoT system in different industries is established. At the same time, a congestion control algorithm based on the application layer is proposed. This algorithm can greatly enhance the adaptability and controllability of the communication network of the IoT. Moreover, when the system is in normal operation, the algorithm can reasonably allocate and optimize bandwidth resources, thus greatly saving network traffic. The algorithm tests the current network state through the network test module, and then determines whether the data is sent according to the test results to ensure that the system has sufficient resources to respond to the sudden situation.
