Blockchain versus IOTA Tangle for Internet of Things

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.
