Abstract	Without the Internet of Things (IoT), there is no smart home, smart city or smart system. It is at the vanguard of the industrial revolution. Engineers need a proper understanding of its architecture to design an optimal system. This chapter presents a comparative analogy on the best architecture for IoT implementation. It seeks to review contemporary IoT architectures and analyse their drawbacks. A critical review of blockchain, IOTA and IoT architecture is done. The study reveals the underlying architecture of low-constrained IoT devices. The IoT devices require a specialized protocol for seamless communication within the network. A review of the consensus protocol and data structure of the two distributed ledger technologies (blockchain and IOTA) enlist IOTA as a relatively better alternative for the low-constrained IoT devices. On this premise, the chapter presents a promising IOTA Tangle as a possible better solution for IoT implementation. © 2022 selection and editorial matter, Sonali Vyas, Vinod Kumar Shukla, Shaurya Gupta, and Ajay Prasad; individual chapters, the contributors.
