Research Summary

In recent years there has been a tremendous growth in the demand for high fidelity multimedia content delivery in wireless networks for applications such as video conferencing, interactive gaming and surveillance. This fact, combined with the development of cutting edge wireless communication technologies such as Orthogonal Frequency Division Multiplexing (OFDM) has led to the advent and standardization of ultra high-speed 4G wireless standards such as LTE, WiMAX and 802.11n. Such networks are envisaged to support high definition video content delivery on demand and ensure proportionally fair QoS of transmission. However, realizing such a paradigm over existing wireless solutions is extremely challenging due to the harsh nature of the wireless channel combined with the existing inefficient wireline based multimedia transmission schemes.

Our efforts are focused towards the development of state-of-the-art solutions to statistically characterize the quality of the video content and for dynamic resource allocation in 4G wireless networks. This will in turn optimize the delivery of multimedia content over various protocols, while utilizing the bandwidth resources efficiently. The objective of the research initiatives is to intelligently combine aspects of 4G communication with novel video processing schemes to develop efficient video/multimedia transmission algorithms that ensure reliability of the received content, while efficiently utilizing the bandwidth resources. This in turn will have a tremendous impact on the speed, scale and robustness of such wireless multimedia applications.
