Abstract
In the field of applied IoT, a large number of wireless sensor devices are tasked with data production and collection, providing IoT subjects with a large amount of basic data to support top‐level IoT applications. However, there is a considerable risk of being attacked on such sensor networks that are organized in a wireless form. These relatively independent network devices have extremely limited performance and lifetime, a problem that can be supplemented in a centralized network with base stations by relying on the performance of the core nodes of the network, but in a decentralized self‐organizing network, they can have a serious adverse impact on the implementation of security solutions. Considering the fundamental nature of the data generated by such end devices in IoT application services, the protection of their security is also directly related to the quality of upper layer services provided. The main research result of this paper is the design of a trust routing scheme for self‐organizing networks. The scheme is based on a comprehensive evaluation of data transmission rate, transmission delay, and other factors related to the operation status of the self‐organized network and improves the efficiency of the overall work of the self‐organized network by reducing the performance consumption of individual nodes of the self‐organized network and balancing the network load.
Highlights
With the popularization and development of Internet technology, the old Internet infrastructure services gradually fail to meet the demand for Internet application services
This threat is reflected, on the one hand, in the fact that low-protection Internet of Things (IoT) terminal devices are more likely to be affected by network attacks, and on the other hand, when a large number of lowprotection devices with network data transmission capabilities are controlled by a network attacker, the attacker can use this as a basis to further expand the threat of network attacks
According to the predictions [1] made by Cisco, a leading provider of network equipment and services, regarding the data transmission during the operation of global networks, using 2018 statistics as a basis, Cisco believes that the number of data network users worldwide will increase 51% by 2023 from 3.9 billion in 2018, while there will be 29.3 billion network devices connected to the global Internet, in which the development of IoT technology has played an important role
Summary
With the popularization and development of Internet technology, the old Internet infrastructure services gradually fail to meet the demand for Internet application services. As a direct result of these problems, the applications built on the IoT infrastructure framework cannot guarantee the security and reliability of their application services They indirectly affect the reliable operation of other networks, as controlled IoT devices can be used to launch new network attacks. This risk poses a significant threat to IoT technologies, which rely on extensive data collection and remote interaction, with extremely high data transmission reliability requirements. A corresponding information maintenance mechanism to maintain and respond to network state changes is designed
