Efficient Trust Management for Blockchain-Enabled Smart City and Medical IoT with Eigenvector-Based ETMS

Safe environment is aimed at creating within the context of Internet of Things (IoT) networks through the use of the Enhanced Trust Management System (ETMS) with the capability of detecting and eliminating the presence of malicious nodes and their contributions from the trust data. This is achieved using an eigenvector technique, which is integrated into a smart contract during the entire process. This allows edge nodes to invoke the contract at any time when it is necessary to invoke contract. To further enhance the security of the compiled trust information, the trust information is stored within a blockchain in blocks. As for routing the packets to the desired destinations, the result of the simulation demonstrates that ETMS is more effective than the systems currently in existence. In contrast to the systems that are currently in use, the suggested mechanism has a tool that will enable detection of contributions that have been faked in dispersed contexts and will therefore overcome a major deficiency. Moreover, the integration of ETMS into a number of circumstances that involve the Internet of Things, for example, Smart Cities, Medical IoT, and Industrial IoT, is entirely possible without any sort of complications. In the same regard, there is need to undertake further assessment on the capability of ETMS operating in real time across all these scenarios.
