Over the past decade, Unmanned Aerial Vehicles (UAVs) have provided pervasive, efficient,
and cost-effective solutions for data collection and communications. Their excellent mobility …

The design of sustainable wireless sensor networks (WSNs) is a very challenging issue. On
the one hand, energy-constrained sensors are expected to run autonomously for long …

Wireless sensor networks (WSNs) have emerged as an effective solution for a wide range of
applications. Most of the traditional WSN architectures consist of static nodes which are …

The concentration of data traffic towards the sink in a wireless sensor network causes the
nearby nodes to deplete their batteries quicker than other nodes, which leaves the sink …

In a typical wireless sensor network, the batteries of the nodes near the sink deplete quicker
than other nodes due to the data traffic concentrating towards the sink, leaving it stranded …

A large class of Wireless Sensor Networks (WSN) applications involve a set of isolated
urban areas (eg, urban parks or building blocks) covered by sensor nodes (SNs) monitoring …

We focus on energy-efficient circular maneuvering and communication for a small
unmanned aerial vehicle (UAV)-based relay, acting as a communication relay for connecting …

Abstract Recently, the Internet of Things (IoT) had emerged very rapidly and became the
most important technology in today's era. In an IoT-based environment, every physical object …

The advances in hardware manufacturing technologies and wireless communications
enabled the evolution of tiny, multi-functional, low-power and resource constrained sensor …

In wireless sensor networks (WSNs), one major challenge is how to prolong the network
lifetime while maintaining a certain data collection rate for resource-limited static sensors. To …
