Journal ArticleDOI

Web Enabled Plant Disease Detection System for Agricultural Applications Using WMSN

TL;DR: A novel web enabled disease detection system (WEDDS) based on compressed sensing (CS) is proposed to detect and classify the diseases in leaves and statistical based thresholding strategy is proposed for segmentation of the diseased leaf.
Journal ArticleDOI

Experimental study on structural, optoelectronic and room temperature sensing performance of Nickel doped ZnO based ethanol sensors

TL;DR: In this article, X-ray diffraction (XRD) analysis proved the hexagonal Wurtzite structure of ZnO and 5, 10, 15 and 15 Wt. % (1ZN, 2ZN and 3ZN) of Nickel doped nanorods were fabricated using the hydrothermal approach on Fluorine doped Tin Oxide (FTO) glass substrates.
Journal ArticleDOI

Energy-efficient image transmission in wireless multimedia sensor networks using block-based Compressive Sensing

TL;DR: The proposed compressed sensing (CS)-based image transmission method has a considerable reduction in energy consumption and better image quality than the conventional CS method and produces better results at a lower sparsity range.
Journal ArticleDOI

Direct laser fabrication of five-band symmetric terahertz metamaterial with Fano resonance

TL;DR: In this paper, a planar multi-band metamaterial with closely spaced band resonance for sensing application is presented, where a rapid direct writing process using ultrafast laser was adopted for fabricating the proposed multiband MM structure.
Proceedings Article

Network lifetime enhancement in wireless sensor network using network coding

M. Nagajothy, +1 more
TL;DR: The proposed solution is more efficient than no-network coding solution while still meeting the required lifetime constraints and improves the lifetime of the network when network coding is being applied.
