The efficient transmission of multimedia applications and time sensititive applications in particular, over the heterogeneous networks is a challenging research problem that requires investigation. This paper focuses on an experimental testbed designed to verify the theoretical concept; performance of multimedia content can be improved by optimizing both network and application. User-driven parameter ‘latency’ was used to achieve the objective, during transmission of multimedia files (video, audio, graphics, and text) over a wireless network. Results indicated that latency factor was reduced significantly, when optimization technique was applied on both network and multimedia content as compared to applying on each component individually. This work falls within the scope of “Optimization Technique for Implementation of Blended Learning in Constrained Low Bandwidth Environment” [1].
