One of the critical parameters of Wireless Sensor Networks (WSNs) is node lifetime. There are various methods to increase WSN ode lifetime, the clustering technique is being one of them. In clustering, selection of a desired percentage of Cluster Heads (CHs) is erformed among the sensor nodes (SNs). Selected CHs are responsible for collecting data from their member nodes, aggregating the ata an...

For the past few years, centralized decision-making is being used for malicious node identification in wireless sensor networks (WSNs). Generally, WSN primary technology to support operations, and security issues are becoming progressively worse. In order detect nodes WSN, a blockchain-routing- trust-model-based jellyfish search optimizer (BCR-TM-JSO) created. Additionally, it provides complete...

This paper investigates the transceiver design problem in a noisy-sensing noisy-transmission multi-input multioutput (MIMO) wireless sensor network. Consider a clusterbased network, where multiple sensors scattering across several clusters will first send their noisy observations to their respective cluster-heads (CH), who will then forward the data to one common fusion center (FC). The cluster...

Due to the advanced developments in communication technologies, Internet of vehicles and vehicular adhoc networks (VANET) offers numerous opportunities for effectively managing transportation problems. On other, cloud environment needs disseminate emergency message which are consistently distributed on roadway so that every vehicle gets messages from closer a straightforward way. To resolve thi...

The main constraint of wireless sensor networks (WSNs) is the limited and generally irreplaceable power source of the sensor nodes. Therefore, designing energy saving routing algorithm is one of the most focused research issues. In this paper, we propose an energy aware routing algorithm for cluster based WSNs. The algorithm is based on a clever strategy of cluster head (CH) selection, residual...

Wireless Sensor Networks have formed new opportunities across the variety of human efforts including engineering design, forest fire tracking, and battlefield surveillance. It is a group of sensor nodes that comprised of sensing, computing, and communication elements that gives an administrator the ability to observe and react to events and phenomena in a specified environment. Minimizing Energ...

Ensuring the freshness of high Value Information (VoI) data has a significant practice meaning for marine observations and emergencies. The traditional forward method with an auv-aid is used to ensure VoI data. However, methods suffer from two issues: insufficient throughput random forwarding cluster heads (CHs). AUV (Autonomous Underwater Vehicle) limited energy cannot meet demand generation L...

In Wireless Ad hoc Networks (WANET), to organize sensor nodes for data collection is an important research issue. Clustering is an effective technique for prolonging the network lifetime. However, the Cluster Header (CH) in a cluster always involves a lot of data forwarding tasks, rather than its Cluster Members (CMs). This energy consumption overloading inevitably leads to the “hot spot” probl...

The design of efficient communication protocols for wireless sensor networks has aroused great interest in the research community, especially face limited energy nodes and frequent change network topology. Routing remains a challenging problem communications, as deploying or replacing hazardous environments is difficult. Many studies have been devoted to alleviate certain limitations, such clus...

Security has played a major role in cognitive radio networks. Numerous researches have mainly focused on attacking detection based on source localization and detection probability. However, few of them took the penalty of attackers into consideration and neglected how to implement effective punitive measures against attackers. To address this issue, this article proposes a novel penalty mechani...
