Energy Efficient Image Compression in Wireless Sensor Networks

Wireless Sensor networks are battery powered due to which their lifetime is very limited. In camera an equipped wireless sensor node, life time of sensor network is decreased quickly due to battery and processing power constraints when image is processed and is transferred to the destination. The image compression not only helps to reduce the communication latency but also gives energy efficiency in wireless sensor networks. In this paper, we present a novel technique, Image Subtraction with Quantization of image (ISQ). We have shown that ISQ improves the energy efficiency of each node of the sensor networks consequently the lifetime of the sensor network is increased.
