Abstract: The internet of medical things (IoMT) includes accessibility and is adequate for medical areas. Diverse techniques are developed based on cloud storage for IoMT applications, but these methods failed to obtain sufficient security in less time. In this research, a Jaya war strategy optimisation (Jaya WSO)-based cloud storage in a blockchain network is introduced for IoMT. Firstly, transactions are generated in IoMT and fed to the base station (BS). Then, it is passed to peers in the blockchain and the ledger is stored in respective peers. For each peer, blocks are selected optimally by Jaya WSO, which is an integration of the Jaya algorithm with war strategy optimisation (WSO) and the multi-objectives. The Jaya WSO attained minimal query probability, storage cost and local space occupancy of 0.428, 20.766 and 52.7 respectively and maximal values of trust level and sensitivity level of 0.849 and 0.916 respectively for block size = 2.

Keywords: internet of medical things; IoMT; blockchain; Jaya algorithm; war strategy optimisation; WSO; cloud storage.
