A global energy efficient wireless sensor network data routing protocol typically uses few suitably located sensors to relay other sensors’ data. These overused sensors reasonably consume more energy and become inactive earlier. Some other sensors then take their role of relaying other sensors’ data. At some point in this cycle, a sensor with sufficient(More)
A photocatalytic fiber was prepared by modifying the surface of jute fiber with a Bi2O3/TiO2 composite. Maleic acid was used as an organic linker, and the coating process was conducted with heat-treatment at 240 °C. At first, the Bi2O3/TiO2 composite was synthesized by incorporating TiO2 nanoparticles onto a Bi2O3 phase. Subsequently, the photocatalytic(More)
In this Letter, we demonstrate for the first time that by combining the effects of the Wood-Rayleigh anomaly (WRA) and the Fabry-Perot (FP) resonance, transmission efficiencies of one-dimensional metallo-dielectric gratings on substrates can be significantly improved compared to when these two phenomena work separately. Results of combining the WRA and the(More)
The demonstration will provide the simulation of intelligent multi-hop techniques to maximize network lifetime. Different routing techniques would be compared using data visualization. Moreover, telos-based motes will be used to demonstrate the implementation of proposed techniques in a realtime embedded operating system such as TinyOS. The motes will be(More)
