Abstract: To solve the problems in Internet of Things (IOT), such as high coupling between levels, low reusability and massive data processing difficulty, this paper proposed a Web service-based middleware model of IOT. It used XML file to configure and implement logical separation, achieved function modularization by the application of "object" in IOT, distributedly processed massive data by load balance, and ensured information security by role permissions setting. The experimental results show that, the middleware model reduces reliance on the type of gateway, improves the reusability of the program and achieves ten-thousand data processing. According to the application of middleware system developed by the model in the vehicle monitoring, the cost of development is reduced, the efficiency of development is improved and the system has a flexible configuration.
