Abstract
Systems and methods for providing content-aware adaptation of multimedia communications in wireless networks to ensure Quality of Experience (QoE) of the content transmitted by the multimedia communications are generally disclosed herein. One example embodiment includes adaptive streaming optimization techniques, such as the exchanging of application-layer parameters used to establish network connectivity settings and implement an appropriate QoE for applications communicating within the wireless network. Example embodiments may also determine and implement Quality of Service (QoS) parameters for the wireless network and other connected networks based on the application-layer parameters. Such application-layer parameters may include receiver display capabilities and multimedia-specific parameters. These techniques may be used in connection with, for example, the transmission of real-time multimedia content, such as multimedia content communicated wirelessly from a computing device using a Wireless Display (WiDi) transmission standard.
