Computer-based solutions that improve the quality of practical services are becoming increasingly popular as the world becomes more urbanised. Most present research on decentralised IoT applications focuses on a particular vulnerability. In contrast, for IoT-enabled industrial applications, only a few mechanisms address the challenges of privacy and trust. In addition, the current plans are in a poor state of repair. such as decentralised mobile networks when time is of the importance, like long-term evolution (LTE-A) The following is an example: Because of its trust-awareness and seamless authentication, TABSAPP is able to address issues of privacy, security, and delivery ratio. The redesigned traffic arrangement and the proposed method both make advantage of this technique. TAB-SAPP is shown to be a viable solution through the usage of identity management. boosts the number of active users by delivering more packets, which results in more mobility.

Moreover, it consists of several tiny sensors to sense the environment and gather the information. These devices continuously monitor, collect, exchange, analyze, and transfer the captured data to nearby devices or servers using an open channel, i.e., internet. However, such centralized system based on IIoT provides more vulnerabilities to security and privacy in IIoT networks. In order to resolve these issues, we present a blockchain-based deep-learning framework that provides two levels of security and privacy. First a blockchain scheme is designed where each participating entities are registered, verified, and thereafter validated using smart contract based enhanced Proof of Work, to achieve the target of security and privacy. Second, a deep-learning scheme with a Variational AutoEncoder (VAE) technique for privacy and Bidirectional Long Short-Term Me...

The interconnection of devices means there is the possibility of challenges such as security, trustworthiness, reliability, confidentiality, and so on. To address these issues, we have proposed a novel group theory (GT)-based binary spring search (BSS) algorithm which consists of a hybrid deep neural network approach. The proposed approach effectively detects the intrusion within the IoT network. Initially, the privacy-preserving technology was implemented using a blockchain-based methodology. Security of patient health records (PHR) is the most critical aspect of cryptography over the Internet due to its value and importance, preferably in the Internet of Medical Things (IoMT). Search keywords access mechanism is one of the typical approaches used to access PHR from a database, but it is susceptible ...

In the recent decade, it has been noted that the demand for this emerging technology is gradually increased with cost-effective results. Although this technology offers extraordinary results, but at the same time, it also offers multifarious security perils that need to be handled effectively to preserve the trust among all engaged stakeholders. For this, the literature proposes several authentications and data preservation schemes, but somehow they fail to tackle this issue with effectual results. Keeping in view, these constraints, in this paper, we proposed a lightweight authentication and data preservation scheme for IoT based-CPS utilizing deep learning (DL) to facilitate decentralized authentication among legal devices.

A comparative analysis of routing protocols such as Ad-hoc On-demand Distance Vector Routing System (AODV), Dynamic Source Routing (DSR) and Optimized Link State Routing (OLSR) is been evaluated with respect to different network parameters like network end to end delay ,load, and throughput in different scale of sensor network scenarios to analyses the best performing protocol. It has been observed that Simulation results indicate that OLSR gives minimum network load in all three scenarios while AODV gives best throughput in small scale network but in medium and large scale networks, DSR is better. So with respect to terms of delay, OLSR is more efficient in small and medium scale network while AODV is insignificant improved in large networks. Apart from this the concept of cooperative communication using WSN is also implemented and the outcome o...
