Radio Frequency Energy Harvesting and Management for Wireless Sensor Networks
Radio Frequency (RF) Energy Harvesting holds a promising future for generating a small amount of electrical power to drive partial circuits in wirelessly communicating electronics devices. Reducing power consumption has become a major challenge in wireless sensor networks. As a vital factor affecting system cost and lifetime, energy consumption in wireless sensor networks is an emerging and act...
متن کاملEnergy Harvesting in Wireless Sensor Networks
Wireless Sensor Networks (WSNs) enable many vital applications ranging from environmental monitoring to human health control. Main research efforts in the WSNs focused on minimizing energy consumption because wireless sensor nodes are mostly powered by batteries which are usually hard to replace. Recent research on long-lasting WSNs is proposing energy harvesters combined with rechargeable batt...
متن کاملEnergy Management for Time-Critical Energy Harvesting Wireless Sensor Networks
As Cyber-Physical Systems (CPSs) evolve they will be increasingly relied on to support time-critical monitoring and control activities. Further, many CPSs that utilize Wireless Sensor Networking (WSN) technologies require energy harvesting methods to extend their lifetimes. For this important system class, there are currently no effective approaches that balance system lifetime with system perf...
متن کاملEnergy harvesting of radio frequency and vibration energy to enable wireless sensor monitoring of civil infrastructure
To power distributed wireless sensor networks on bridges, traditional power cables or battery replacement are excessively expensive or infeasible. This project develops two power harvesting technologies. First, a novel parametric frequency-increased generator (PFIG) is developed. The fabricated PFIG harvests the non-periodic and unprecedentedly low frequency (DC to 30 Hz) and low acceleration (...
متن کاملOutage Probability Minimization for Energy Harvesting Cognitive Radio Sensor Networks
The incorporation of cognitive radio (CR) capability in wireless sensor networks yields a promising network paradigm known as CR sensor networks (CRSNs), which is able to provide spectrum efficient data communication. However, due to the high energy consumption results from spectrum sensing, as well as subsequent data transmission, the energy supply for the conventional sensor nodes powered by ...
