Design and implementation of the transmission scheme of the sensor data based on the CoAP protocol

With the implementation of the national internet plus strategy, more and more devices enjoy the chances of getting access to internet. But for devices like sensors whose resources are quite limited, it is a tremendous challenge to link to the Internet by using the traditional communication methods. Taking the memory size, computing power and energy consumption of the resource-constrained device into consideration, we design and implement a set of sensor data transmission scheme to meet the needs of the safety monitoring of enterprise manufacture based on the Constrained Application Protocol (CoAP) in this thesis. In the end, the validity of the transmission scheme is verified by experiments.
