In this paper, a communication system based on LwIP protocol stack which can process and transmit high redundancy data is proposed. This system is composed of upper computer layer, middle server layer and bottom sensor layer in order to satisfy requirement of IoT data transmission. The middle server layer is set up to control a ISR (Interrupt Service Routines) window to answer the request from bottom sensor layer and collect data. The key data is extracted according to the data filtering algorism. The encapsulated data is transmitted to the upper computer layer through the network interface based on LwIP protocol stack in middle server layer as well. This system can not only reduce the redundancy of data in the IoT and the occupancy of system resources, but also improves the real-time performance of the IoT communication system.
