 We simulate an application of IoT in a master-slave model. The slave device establishes a TCP connection to the master with the IP address set by the user program through ioctl, which present the server collecting the data from specific device. In contrast, the master device listens on a specific TCP port when the module is loaded into the kernel. We simulate an application of IoT in a master-slave model.
