Energy Efficient and Secure Image Communication over Wireless Network

In this paper Wireless Sensor Networks (WSNs) are a collection of tiny nodes,. These nodes are typically battery-operated and their recharge or replacement may be undesirable or not possible. Thus, energy consumption is a key issue in the design of WSNs. The large amount of data traffic for image transmissions over a WSN can rapidly shorten the lifetime of the network, So a strategy to mitigate this problem is to promote some sort of image data compression. Recent works have investigated image transmission in WSNs, and many of them employ wavelet-based image compression. Steganography is the art of hiding the existence of data in another transmission medium to achieve secret communication. It does not replace cryptography but rather boosts the security using its obscurity features. Steganography method used in this paper is based on biometrics in skin tone region of images. Here secret data is embedded within skin region of image that will provide an excellent secure location for data hiding. This study shows that by adopting collaborative method of compressed image communication we get energy efficient network.
