Novel Internet of Things access mode based on anti-cheating random number

Abstract

The invention discloses a novel Internet of Things (IoT for short) access mode based on an anti-cheating random number. A traditional IoT access mode requires all IoT devices to comply with a random access criterion honest, but network fairness and overall efficiency will be seriously destroyed when a node has a selfish access behavior. According to the novel IoT access mode provided by the invention, the anti-cheating random number is utilized, and under the constraint of the access mode provided by the invention, the IoT devices which are not trusted with each other are forced to strictly comply with the random access criterion, so that the fairness and efficiency of the network are ensured. The access mechanism based on the anti-cheating random number is safe, reliable, small in calculated amount, easy to implement and suitable for general IoT equipment with low power consumption and low computing power.

Description

technical field [0001] The invention relates to the technical field of Internet of Things device access, in particular to a novel Internet of Things access method based on anti-cheating random numbers. Background technique [0002] In recent years, the rapid development of Internet of Things technology has aroused the research interests of the industry and researchers. Among them, the access technology of devices in the Internet of Things (Internet of Things, IoT) network is one of the core technologies of IoT. With the continuous expansion of IoT scale, the problem of device access in IoT network becomes more and more obvious. Most of the existing IoT devices follow the random access rule. In the process of requesting access, once a device collides or collides, random backoff is performed to reduce the probability of network conflicts and improve the overall efficiency of the network. [0003] It should be noted that existing random access protocols are designed for scena...

Problems solved by technology

However, with the development of IoT technology, the number of IoT devices will increase exponentially. In practice, IoT networks usually contain a large number of devices from different operators or manufacturers, which means that in the above environment, the number of IoT devices unable to gain a high level of trust and cooperate with each other

At this time, some malicious devices can ignore the random access criterion, and selfishly occupy the access channel resources to achieve faster access without the constraint of backoff time, and then induce other devices to take the same behavior, eventually leading to shared channel severe congestion
