Abstract: A novel MPEG-4 video cross-layer algorithm (MVCLA) is applied in the wireless network platform to approach the higher quality of service (QoS) in various prioritised traffic flow of MPEG-4 video applications. Even the popular availability of delivering the wireless network access data by the enhanced distributed coordination access (EDCA) mechanism function, the proposed MVCLA considers two variant conditions (i.e., data packets and network traffic load) to tune the contention-based parameters of cross-layers. The queue space does not effectively resume the transmission quality for the most important video media when the traffic flow is heavy. Our proposed regulation way dynamically retained the most important image traffic flow information in various conditions. The access control (AC) queue is flexibly allocated for the transmission purposes while the network channel is busy. The novel tuning algorithm is not only to ensure the high-speed for the most important packets to pull up the QoS level in several video transmission applications, but also efficiently provide the higher utilisation of the queue length. Finally, higher QoS of MPEG-4 video application is actually to verify the great simulation by the developed MVCLA.
