Energy Aware Adaptive Image Transmission Scheme with Data Authentication in Wireless Sensor Networks
Wireless Multimedia Sensor Networks (WMSNs) are gaining
research interest due to the availability of low-cost cameras
and CMOS image sensors, also due to their broad application
opportunities. The energy and resource constrained
environment of WMSNs calls for low complexity energy
aware image authentication and transmission schemes with
minimal overheads. The proposed scheme enhances the data
security with stream authentication while minimising the
energy utilization for the authentication as well as
transmission by adopting a preferential transmission based on
the importance of the data packets in the code stream.
Inherent correlation among neighbouring pixels in an image
and the multi resolution capability of wavelet coding is
exploited to propose an adaptive priority based image
authentication and transmission scheme. Simulation results
show an encouraging and improved energy efficiency without
compromising reconstructed visual quality.
Keywords: DWT; scalable; stream authentication; WMSNs.
