Abstract: This paper presents the JPEG image wireless transmission system based on wireless
sensor network. This system uses OV528 as the compression chip of JPEG image and JN5121
which supports ZigBee protocol as the core chip of data transmission. This WSN system which adopts MESH topology can transmit the image data. The JPEG image wireless remote transmission system based on ZigBee protocol has the characteristics of simple structure, easy installation, low cost and high applicability, so it could be widely applied in many fields including the disaster monitor, automobile guard against theft and security monitor, etc.
Keywords: Image remote transmission, JPEG image compression, ZigBee protocol
