As an energy-efficient strategy, node sleep scheduling has become a hot topic of the energy
conservation in wireless sensor networks (WSNs). Among these strategies, the N-policy …

WSN consist of set of Sensing points which are responsible for collecting the detected
information and then send the packets towards control centre which is responsible for …

Abstract In Wireless Sensor Networks (WSNs), the packet congestion will lead to high delay
and high packet loss rate, which severely affects the timely transmission of real-time packets …

Most research on the mathematical modelling of wireless sensor networks (WSNs) have
focussed mainly on the optimization aspects, such as those relating to sensor placements …

The increasing interest in Wireless Sensor Networks (WSN) can be understood to be a result
of their wide range of applications. However, due to uneven depletion of their batteries, the …

Inventions in electronics and communication industries increased rapidly the utilization of
wireless sensor networks, still the selection of the routing algorithm is done application wise …

Efficiently allocating the scarce and expensive radio resources is a key challenge for
advanced radio communication systems. To this end, cognitive radio (CR) has emerged as a …

This paper considers a queue-based technique for the improvement of the lifetime of
wireless sensor networks (WSNs). We investigate the impact of queueing scheme on the …

Wireless sensor networks usually consist of a large number of very small, energy-
constrained sensor nodes. The nodes capture information from their immediate environment …

In this paper, we analyze the power consumption of wireless sensor nodes with min (N, T)
policy and M/G/1 queue in the presence of Nakagami-m fading. In particular, this system …
