Integrated Sensor Wireless System for Alternative Energy Applications

Abstract

Abstract-These Wind turbines convert mechanical energy into electrical energy for storage and consumption. Pressure transducers are important in reflecting pressures within the hydraulic cylinders; they can provide continuous and reliable operation that enhances the reliability and efficiency of the overall system. Monitoring high temperature fluctuation will be necessary for the resolution and efficiency of the system. An integrated sensor system should be important for monitoring the tower vibration for bending, crack formation, and wave vibration.Smart nanotechnology materials have been recently utilized in sensing applications. Carbon nanotube (CNT) based SoC sensor systems have potential applications in various fields, including medical, energy, consumer electronics, computers, and HVAC (heating, ventilation, and air conditioning), among others.In this study, a nanotechnology multisensory system was designed and simulated using Labview Software. More emphasis are given to both pressure and temperature sensors that serve as transducers for the power mills. The mathematical models were developed for sensing three physical quantities: temperature, gas, and pressure. Four CNT groups on a chip (two for gas sensor, one for temperature, and a 4 th one for pressure) were utilized in order to perform sensing multiple parameters. The proposed fabrication processes and the materials used were chosen to avoid the interference of these parameters on each other when detecting one of them. The simulation results were translated into analog voltage from Labview software, transmitted via Bluetooth network, and received on desktop computers within the vicinity of the sensor system. The mathematical models and simulation results showed as high as 95% accuracy in measuring temperature, and the 5% error was caused from the interference of the surrounding gas. Within 7% change in pressure was impacted by both temperature and gas interference.Index Terms-Wind energy, nanotechnology, pressure sensors, temperature sensors, SOC.

MDA-SMAC: An Energy-Efficient Improved SMAC Protocol for Wireless Sensor Networks

“…Schedule-based protocols support fairness by scheduling when a node can get access to the channel. Due to the inability to maintain the schedule when the traffic and topology changes are major problems of this kind of protocol, TRAMA [24] [25] and FLAMA [26] [27] utilize CSMA [28] [29] periods to allow new nodes to join the network, while VTS [30][31] adaptively adjusts super frame length according to the number of nodes in range. To cope with heavy traffic, nodes of TRAMA and FLAMA release their unused slots, while VTS reduces the sleep interval.…”
