Tangent Pelican search optimization for block assignment in blockchain based IoT

Recently, academia has made huge attempts to exploit the blockchain technique to deal with security susceptibilities caused by IoT features. Here, the design of a secured Internet of Things (IoT) with blockchain is implemented for separately dealing with IoT security. This paper develops an optimum blockchain deployment method for blockchain-based IoT, in which devices concerning IoT pose fewer resources which are susceptible to enhance efficiency and acquire the best blockchain and communication procedure integration. Initially, the Blockchain based IoT platform is simulated, in which the assignment of an optimum block is executed. Here, the complete blockchain is maintained with IoT nodes in a joint manner to ensure each node transaction is checked. Hence, dynamic adjustment of optimal block assignment can help to achieve better balance amid the blockchain length and security. In addition, a Tangent Pelican Optimization Algorithm (TPO) with fitness parameters like Signal to Noise Ratio (SNR), storage occupancy, and distance is devised. The optimal block assignment allocates blocks individually with Function Node (FN) and Consensus Unit (CU). The TPO conquered better efficacy with the fitness of 0.465, Average occupancy storage rate (AOSR) of 0.636 and computation time of 0.973 respectively.
