Abstract

The invention relates to a dynamic CoAP mode selection method and device based on UCB, and the method comprises the steps: obtaining the type of a data transmission mode of a CoAP protocol in a current data transmission scene, and determining the optimal data transmission mode of each data packet in a data transmission process based on an MAB transmission model. As the MAB transmission model is an online learning model, the data transmission mode combination strategy in the following transmission process can be determined in real time according to the transmission performance of the data packets which are transmitted in the data transmission process, so that the balance between the data transmission time delay and the packet loss rate is achieved on the whole, and the overall performance of the system is improved.

Description

Technical field [0001] The present application relates to the field of Internet of Things data transmission technology, and more particularly to a dynamic restricted application protocol based on UPPERCONFIDENCE Bound, a COAP mode selection method and device. Background technique [0002] With the application and development of the Internet of Things technology, "cloud" and "edge", "side" and "side" and "end" are interactive, and the device is plug-and-play, and the device is widely connected. And key points and focus of related business processes, communication protocols are an effective carrier that implements information interaction. The COAP protocol is the resource restricted application protocol in the Internet of Things. It solves the network congestion of high-concurrent business in the power distribution network in a smaller packet and faster transfer period, and supports DTLS encryption. The equipment is self-description to perform a point table configuration, realizing...
