Wireless Image Sensor Networks: A Review

Wireless sensor networks (WSN) were extensively used in monitoring and observing a particular region. WSN are combination of nodes and can be sensitive to pressure, temperature, motion, sound etc. This paper represents the survey of design and implementation of Wireless Image Sensor Network, which is an integral part of monitoring and surveying the subjective region visually. Image sensor nodes are equipped with miniature visual camera and RF module for communication. The camera node provides visual information and then transmitted to another node wireles sly using ZigBee. Several challenges in sensor networks are discussed that can enhance performance and efficiency of modern day sensor networks, As it turns out FPGA can reduce computational cost through onboard image processing. We have discussed in the subsequent part about the combination of microcontrollers and FPGA which can play a major role in areas where processing capabilities such as compression, cryptography, and transmission of data are important.
