In the past, the existing Internet of Things caused traffic congestion and receiver uncertainty problems due to insufficient data transfer between the nodes or devices for data perception. The authors have proposed the method for context-aware data perception in the cognitive internet of things environment. The proposed context-aware data perception is described in the following stages, initially nodes in Cognitive Internet of Things network are clustered effectively using adaptive pillar ‘K' means clustering algorithm. After the formation of effective clusters, the cognitive agent performs the effective context-aware data learning using support-based convolutional neural networks. Finally, adaptive fuzzy logic defines the effective decision for data perception. The experimental results show that the proposed method outperforms the cognitive agent approaches of data perception in terms of network lifetime, energy consumption, data perception accuracy, and throughput in the cognitive internet of things.

This article deals with the implementation and experimental verification of the suitability of the TinyIPFIX protocol for data transmission in the Internet of Things environment. The work was devoted to the creation of three main components, namely TinyIPFIX exporter, collector, and mediator. The implementation of these tools made it possible to extend the possibility of monitoring a common network with an IoT environment. The experiments confirmed the success of the implementation of the protocol based on standards and pointed out the suitability of the implementation of the TinyIPFIX protocol mainly due to its optimized processes, which save up to 72% of bandwidth consumption compared to the IPFIX protocol when transmitting one data unit. Thanks to the modular approach during implementation, it is possible to deploy the protocol in the environment regardless of the transport technology. The created solution can therefore also be used in UAV sensor networks.

Internet of Things (IoT) is an evolving technology in the current era with a combination of diverse computational technologies, objects, animals and human. The objects in the IoT framework transmit data among themselves and they are assigned with unique numbers for identification. The communication among the network is established by identification system and functions without any centralized system. Advancement in the sensor network has made automation in numerous field and integration of soft computing technology in the IoT system has made effective decision making. The objects resides in the IoT system acts intelligent and perform the actions intelligently. The IoT based technology enhances daily life of humans via connected devices and makes living things context-aware. The information collected from sensors will be processed with the computational algorithms and effective predictions are accomplished. In this article, recent applications and soft computing algorithms are reviewed. In addition to that numerous applications based on IoT is also discussed in this article.

The proliferation of smart devices in the Internet of Things (IoT) networks creates significant security challenges for the communications between such devices. Blockchain is a decentralized and distributed technology that can potentially tackle the security problems within the 5G-enabled IoT networks. This paper proposes a Multi layer Blockchain Security model to protect IoT networks while simplifying the implementation. The concept of clustering is utilized in order to facilitate the multi-layer architecture. The K-unknown clusters are defined within the IoT network by applying techniques that utillize a hybrid Evolutionary Computation Algorithm while using Simulated Annealing and Genetic Algorithms. The chosen cluster heads are responsible for local authentication and authorization. Local private blockchain implementation facilitates communications between the cluster heads and relevant base stations. Such a blockchain enhances credibility assurance and security while also providing a network authentication mechanism. The open-source Hyperledger Fabric Blockchain platform is deployed for the proposed model development. Base stations adopt a global blockchain approach to communicate with each other securely. The simulation results demonstrate that the proposed clustering algorithm performs well when compared to the earlier reported approaches. The proposed lightweight blockchain model is also shown to be better suited to balance network latency and throughput as compared to a traditional global blockchain.
