Due to growing demand for wireless access technology (802.11 standards) the high capacity multimedia transmission over wireless networks pose many challenges, by taking note that video streaming has gained enormous popularity and is accountable for a large fraction of current internet traffic. In order to have an appropriate video transmission over wireless network especially when it comes to large scale users and roaming intensity, many requirements must be considered. Large throughput and minimum delay are the most significant requirements to keep the transmission stable and seamless. Jitter is another important factor in degradation of the quality of received video. To achieve the seamless live video streaming with high quality of service (QoS) different technologies must be studied, such as video encoding/decoding platforms, transmission technologies (unicast/multicast), mobility models and efficient handoff methods. These issues are addressed in this project.
