PEWSN: Power Equilibrium Wireless Sensor Network.
Abstract: In this work
we present the Power Equilibrium Wireless Sensor Network (PEWSN), a novel wireless
sensor network architecture designed to extend the lifetime of wireless sensor networks
(WSNs) and at the same time ensures the predictable and bounded payload latency. To
achieve this objective, PEWSN strives to reach power equilibrium using highly efficient
PEWSN protocol features such ... read moreas PEWSN-specific TDMA schedule, smart cluster head
selection, adjustable communication bandwidth and contention-free reliable
communication. Our architecture also takes advantage of energy harvesting capabilities
of each sensor. PEWSN architecture supports network metamorphism which means the network
is capable of changing its primary sensing objectives and methodologies while running.
PEWSN supports seamless network configuring and re-configuring as well seamless repair
and restructure. PEWSN comes with custom-made OMNET++-based network simulator and
MATLAB-based script. The predictable latency along with the extended network lifetime
makes PEWSN architecture suitable for a wide range of commercial and industrial
applications such as health/environmental/habitat monitoring, inventory tracking, and
process supervision. The architecture is also suitable for military indoor and outdoor
applications such as intrusion detection, critical infrastructure monitoring,
ground/port surveillance, and guidance in case of unexpected
