The importance and the possibilities of wireless sensor networks (WSNs) are now quite
clear, because they can be found in all kinds of applications, from those in our daily life to …

Extending the lifetime during which a wireless sensor network (WSN) can cover all targets is
a key issue in WSN applications such as surveillance. One effective method is to partition …

Wireless Sensor Networks (WSNs) are networks of autonomous nodes used for monitoring
an environment. In designing WSNs, one of the main issues is limited energy source for …

Due to the continuous development and progress of wireless communication technology
and sensor network technology, wireless sensor networks (WSNs) have gradually become …

Wireless sensor networks involve a large area of real-world contexts, such as national
security, military and environmental control applications, traffic monitoring, among others …

One of the most critical issues in wireless sensor networks is represented by the limited
availability of energy on network nodes; thus, making good use of energy is necessary to …

Wireless sensor networks are generally composed of a large number of hardware devices of
the same type, deployed over a region of interest in order to perform a monitoring activity on …

In wireless sensor networks (WSNs), network lifetime and energy consumption are two
important parameters which directly impacts each other. In order to enhance the global …

It is a known phenomenon that in a wireless sensor network, sensors communicating directly
with a sink deplete their energy faster than the others. As a result, the so-called neighboring …

Several studies in recent years have considered many strategies for increasing sensor
network lifetime. We focus on a centralised management scheme where a large number of …
