Secure and error resilient approach for multimedia data transmission in constrained networks

Abstract : This paper addresses the general issue of securely transmitting captured images within constrained networks, as those of Wireless Multimedia Sensor Networks (WMSN)s. In particular, it focuses on handling transmission errors due either to unreliable communications or active attacks. The main objective is to preserve the perceived quality of images, received at the destination node, whilst preserving the net-work resources, mainly communications. To this end, a new scheme, composed on two components, is proposed to defeat against communication errors. The first component consists in a new communication protocol, inspired from the ARQ protocol, at the data-link layer, in order to reduce the num-ber of frames re-transmissions. Combined with the second component which is a novel filtering mechanism to visually correct the received corrupted data at the destination node. Obtained results have validated the powerful strength of the proposed solution to defeat against various types of errors and to enhance the visual quality of images whilst ensuring content reduction and data confidentiality.
