Embodiment Construction

[0052] The specific process of the MAC protocol of differentiated services based on the Internet of Things is as follows:

[0053] Step 1) Define service priority.

[0054] a) According to the current application (audio, video, text information, etc.) service quality requirements, such as data delay, data packet loss rate, etc., set the corresponding service level, that is, the service priority. According to the general application of the Internet of Things, to avoid the high delay of audio and video information and affect the reception effect, here we define the video data as the highest priority 3, the audio data as 2, and the text information as 1. Of course, these settings can be modified according to different applications.

[0055] b) Set the service priority mapping table, and bind the service priority of each level to the corresponding transmission rate.

[0056] Step 2) Define interest messages.

[0057]In the stage of interest diffusion, the sink node periodically...

Abstract

A routing method based on differentiated services of the internet of things relates to design of the routing protocol of the internet of things and is mainly used for providing differentiated services aiming at different services. When the internet of things has audio and video information and probably has text information at the same time, different applications require different QoS, at the time, the designed routing protocol, as required, can provide differentiated services aiming at different services, and effective utilization of resources is simultaneously realized in the total network.The method provides the routing protocol based on the differentiated services of the internet of things, sets the dynamic routing scheme according to the service level, sets the service level according to the service application and completes routing aiming at the services by spreading interest and setting up the route, thus prolonging the life of the internet of things and improving the harmony and the service quality of the internet of things.

Description

technical field [0001] The invention relates to the design of a network layer routing protocol of the Internet of Things, and is mainly used for providing differentiated services for different services. Background technique [0002] The Internet of Things is a distributed sensor network composed of a group of multimedia sensor nodes with perception, computing and communication capabilities. It collects various media information (audio, video, image, etc.) of the surrounding environment through the multimedia sensor on the node, and collects the data to the aggregation node through multi-hop mode to realize comprehensive and effective environmental monitoring. [0003] In IoT, the transmitted data is mainly audio and video data. The amount of video data information is huge. If the video data is continuously transmitted on the wireless link, the wireless channel bandwidth will become the bottleneck of the system. The network will quickly run out of energy, and the life cycle...
