Internet-of-Things (IoT) environment has a dynamic nature with high risks of confidentiality, integrity, and availability violations. The loss information, denial access, information leakage, collusion, technical failures, data security breaches are difficult to predict anticipate in advance. These types nonstationarity one the main issues design reliable IoT infrastructure capable mitigating their consequences. It is not sufficient propose solutions for given scenario, but mechanisms adapt current solution changes environment. In this article, we present multicloud storage architecture called WA-MRC-RRNS that combines weighted access scheme, threshold secret sharing, redundant residue number system multiple failure detection/recovery homomorphic ciphers. We provide theoretical analysis probability loss, redundancy, speed encoding/decoding, show how dynamically configure parameters cope different objective preferences, workloads, cloud properties. multiobjective optimization mechanism adjust encryption-decryption speed, probability. Comprehensive experimental real shows our approach provides secure way mitigate uncertainty use untrusted infrastructure.

The health industry is one of the most auspicious domains for application Internet Things (IoT) based technologies. Lots studies have been carried out in field to minimize use resources and increase efficiency. IoT combined with other technologies has brought quality advancement sector at minimum expense. One such technology wireless body area networks (WBANs), which will help patients incredibly future make them more productive because there be no need staying home or a hospital long time. WBANs an integrated as WBANs, like any application, are collection heterogeneous sensor-based devices. For better amalgamation several hindrances blocking their integration addressed. problem efficient routing data limited resource sensor nodes (SNs) WBANs. To solve this problems, transmission duplicate sensed data, network lifetime, etc., energy harvested cooperative-enabled protocol (EHCRP) IoT-WBANs proposed. proposed considers multiple parameters residual SNs, number hops towards sink, node congestion levels, signal-to-noise ratio (SNR) available bandwidth. A path cost estimation function calculated select forwarder using these parameters. Due path-cost process, mechanism achieves effective multi-hop improves reliability efficiency over network. After extensive simulations, achieved results compared state-of-the-art techniques, i.e., E-HARP, EB-MADM, PCRP EERP. show significant improvement throughout, end-to-end delay.
