Most wireless sensor networks operate with very limited energy sources-their batteries, and
hence their usefulness in real life applications is severely constrained. The challenging …

In Wireless Sensor Networks (WSNs) one of the critical issues is the maximization of their life
time. These networks require a robust architecture that takes into account the energy …

In recent years, the number of wireless sensor network deployments for real life applications
has rapidly increased. Still, the energy problem remains one of the major barriers somehow …

Wireless sensor network (WSN) is a collection of sensor nodes which are deployed densely
in a distributed environment. Energy is biggest constraints to wireless sensor capabilities …

Sensors have limited resources so it is important to manage the resources efficiently to
maximize their use. A sensor's battery is a crucial resource as it singly determines the …

Wireless sensor networks (WSN) with hierarchical organizations have recently attracted a lot
of attention as effective platforms for pervasive computing. With power efficiency and lifetime …

Wireless sensor networks (WSNs) suffer from the lack of wired infrastructure. Each node
needs its own power supply, eg batteries or energy harvesting systems (EHSs). Typically …

Due to the power limitation in wireless sensor nodes, special attention is required in
optimizing the power consumption of the necessary electronics on a node. This can be done …

Wireless Sensor Networks functionality is closely related to network lifetime which depends
on the energy consumption at the node level as well as the network level. Analysis of the …

Knowing available energy in each part of a wireless sensor networks (WSN) is undoubtedly
essential information. A simple approach to achieve this would be for sensor nodes to …
