A dual scheme for secured Multimedia Wireless Sensor Network

In this article a dual scheme for secured Multimedia Wireless Sensor Networks (MWSN) is being presented. The dual scheme is based on: a) the Quad Tree Decomposition algorithm that it is able to compress the images before transmission, while providing significant robustness in retaining the image quality, against packet losses, and b) the Secure and Scalable Rekeying Protocol (S²RP), which encrypts all the data transmissions and is also responsible for the rekeying process in case of a node failure. In the proposed MWSN, a trade off is being made among retaining secured and faster transmission rates against the quality of the transmitted images. Multiple experimental results are presented that prove the efficacy of the proposed scheme.
