Nowadays, the Internet of Things (IoT) is used for the purpose of gathering data through sensors as well as for storing and processing data. Due to the inherent limitations in the processing and computing capabilities of IoT devices, the inclination towards the integration of cloud computing (CC) with IoT systems is growing rapidly. The CC is capab...

The internet of things (IoT) has recently become extremely important in our lives. With the advancement in IoT, wireless sensor networks (WSNs) have gained much importance. In WSNs, the routing of clusters has gained more interest. However, there is still a problem with the hotspot. One way to address this issue is uneven clustering. In these, node...

For a long time, anomaly detection is such a well topic. Its use in the banking industry has aided in the detection of questionable hacking activity. In the network of bitcoin, since all nodes are unlabeled, there is no proof that any particular transaction is the result of illegal activity, this thesis seeks to identify transactions that are unusu...

Nowadays, wireless sensor network (WSN) improves people's lives by assisting them with a variety of applications. The major challenge in WSN is consumption of power as well as lifetime of the network. Clustering is the important method for saving energy in WSN because the separation of the sender and the receiver is related to transmission energy....

Wireless Sensor Networks is a complex network with millions of small-scale sensor nodes, working together to detect certain physical phenomena. Sensor nodes are operated by battery therefore the major concern is energy efficiency. Clustering is an effective technique to decrease the energy depletion in the network. However, choosing the optimum Clu...

Wireless sensor networks (WSN) encompasses millions of nodes that work jointly, senses environmental information, and transmits to the Base Station (BS). “Energy hole” or “hot‐spot” is a problem in which sensor nodes near to the BS deceasetoo early which creates the partitioning of the network. This is due to the reason of the difference in the con...

The fundamental unit of the Internet of Things (IoT) is wireless sensor networks (WSNs). Due to their low cost and prospective use, WSNs have drawn interest in various applications over the last years. Since sensor nodes are equipped with limited battery, it is vital energy consumption be carefully monitored. Therefore, minimizing the node energy c...

A wireless sensor network (WSN) is a prominent technology that could assist in the fourth industrial revolution. Sensor nodes present in the WSNs are functioned by a battery. It is impossible to recharge or replace the battery, hence energy is the most important resource of WSNs. Many techniques have been devised and used over the years to conserve...

Security is the utmost importance for the safe operation of the Internet of Things (IoT) devices. Behind IoT, a sensor network operates. Hence, security and lifetime extensions of the sensor networks are the primary concern. Node clustering is a technique to lengthen the lifetime of sensor networks. In a clustering technique, Cluster Heads (CH) are...

Present study indicates to improve network performances which use cross-layer approach. Application of transmission power control technique to dynamically adjust transmission power results in significant reduction of energy consumption. Along with this, a weight is calculated by considering ‘ED’, associated with each node to reduce control overhead...

Wireless sensor networks (WSNs) is a rapidly growing technology. WSNs comprises of sensor nodes having limited energy as battery powers them. These batteries cannot be changed or recharged as they are operated in a harsh environment. Energy conservation mechanism should be developed. Through study, it is found that clustering is an approach for ach...

The energy consumption in wireless sensor networks is a significant matter and there are many ways to conserve energy. The use of mobile sensors is of great relevance to minimize the total energy dissipation in communication and overhead control packets. In a WSN, sensor nodes deliver sensed data back to the sink via multi hopping. The sensor nodes...
