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 …

Wireless sensor networks (WSNs) are typically used with dynamic conditions of task-related
environments for sensing (monitoring) and gathering of raw sensor data for subsequent …

In the last years, wireless sensor networks (WSNs) have gained increasing attention from
both the research community and actual users. As sensor nodes are generally battery …

In wireless sensor networks (WSNs) nodes often operate unattended in a collaborative
manner to perform some tasks. In many applications, the network is deployed in harsh …

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 …

Several studies have demonstrated the benefits of using a mobile sink to reduce the energy
