| 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 as 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 events. |
