    EDAS– Energy-Efficient Device-based Adaptive Cross-Layer Scheme for Wireless Multimedia Transmission
    Next generation wireless networks are poised to support real-time video-on-demand and high quality multimedia streaming applications. In order to support them, several adaptation strategies have been proposed at different layers of the OSI network stack. Also, certain cross-layer strategies across physical/data link and transport/application layers have been proposed over the years. However, given the battery constraints of a smartphone, it is imperative that new cross-layer design be developed that would bring into account an energyoriented mechanism from a device perspective. In this paper, a new adaptive solution, EDAS – energy-efficient device oriented adaptive cross-layer scheme for multimedia transmission in wireless network environments is proposed. Importantly, EDAS provides a novel framework spanning across several OSI layers that would dynamically vary the energy consumption in mobile devices while maintaining a high peak signal to noise ratio (PSNR) in order to ensure a good video quality. It has been observed that EDAS significantly outperforms other schemes in terms of PSNR, loss-rate and importantly, the energy consumption in device.
