Nowadays, cloud-based storage systems play a vital role in IoT data storage, processing, and sharing. Despite its contribution, the current architecture may cause severe leakage or jeopardize user privacy. Meanwhile, heavily relies on trusted third-party auditor (TPA) runs centralized control manner. However, TPA not be completely trustworthy entity, single point of failure might system to collapse. Fortunately, with advent blockchain technology, decentralized model has gained popularity. A...

A large number of deaths are caused by Traffic accidents worldwide. The global crisis road safety can be seen observing the significant and injuries that traffic accidents. In many situations family members or emergency services not informed in time. This results delayed service response time, which lead to an individual’s death cause severe injury. purpose this work is reduce time like other emergencies such as fire, theft/robberies medical emergencies. By utilizing onboard sensors a...

The paper deals with the computation of solutions fuzzy Volterra integral equations degenerate kernel by applying a hybrid method. proposed method is built on Laplace transform coupled Adomian Decomposition Method; Method abbreviated as (LADM). In considered equation unknown function has solution in terms infinite series expansion and hence LADM becomes more accurate to give exact solution. Firstly, using number term parametric form, converted two crisp then applied get linear equations. For...

Abstract Currently, there is no unified Electronic Health Record (EHR) system connecting major healthcare organizations such as hospitals, medical centers, and specialists. Blockchain technology, with its unique features, provides an ideal platform for developing a large‐scale electronic health record system. In this article, the authors introduce HealthChain, novel blockchain‐based secure EHR that integrates advanced encryption techniques, robust consent management system, cross‐platform...

Cooperation among nodes is mandatory for smooth operation of Mobile Ad Hoc Networks (MANETs) in terms data routing. A participating node may refuse to deplete its resources the benefit others because not getting any direct advantage service. Nodes showing such behavior are called selfish or non-cooperative nodes. Non-cooperative can severely affect performance MANETs. MANETs lead network partitioning. In this paper, we address issue by incorporating concept fuzzy logic closely coupled with...

Abstract In this article, we use a fuzzy number in its parametric form to solve nonlinear integral equation of the second kind crisp case. The main theme article is find semi-analytical solution equations. A hybrid method Laplace transform coupled with Adomian decomposition used equations including Fredholm equation, Volterra and singular Abel type kernel. We also provide some suitable examples better understand proposed method.

In this article, the Volterra integro-differential equation of separable type kernels is considered under fuzzy concept. A hybrid technique used to solve equations notion generalized Hukuhara differentiability. To build up a suitable algorithm, Laplace transformation coupled with Adomian decomposition method (LADM) which an essential and profitable algorithm for setting equations. The proposed illustrated by two test problems that show convergence series solution exact in closed form....

The deficient round robin (DRR) and stochastic fair queue (SFQ) are the active mechanism (AQM) techniques. These AQM techniques play important role in buffer management order to control congestion wired-cum-wireless network by dropping packets during overflow or near overflow. This research study focus on performance evaluation of DRR SFQ using different scenarios such as increasing number node scenario, pause time scenario mobility scenario. We evaluate based two parameters average packet...
