The QR code is a kind of two dimensional barcode, and is invented by a Denso-Wave company in Japan. QR comes from the abbreviation of “Quick Response”, and it can recognize in all locations. This article describes the basic principle and algorithm of distortion and geometry revision on images when QR is recognizing. Then according to the symbol structure of QR code, a effective method of getting image...
Due to the limited energy of wireless sensor networks (WSN), lots of research works have been done with topology algorithm in WSN. To solve the problem of the unbalanced energy consumption and improve the life circle, this paper proposes an Improved Energy Efficient Unequal Clustering (IEEUC) algorithm based on node degree, the clusters closer to the base station have less members than the farther...
As the development of sensor technology and communication technology, the realization of smart home is not longer out of reach. This paper provides a design of smart home system based on wireless sensor network (WSN) within the ZigBee criterion. For the different network condition of different houses, we employ different networks (Internet or UMTS) to achieve remote control of the house's electric...
