An autonomic wireless video transmission system based on GANA

This paper analyzed the autonomic requirements of wireless video transmission. Based on GANA, an autonomic wireless video transmission system was designed, in which both the physical layer and application layer were autonomic. The monitoring mechanisms of physical layer bandwidth and application layer available bandwidth were given. A group of decision-making algorithms were proposed. Simulation result shows that the system is capable of adjusting the physical layer transmission rate according to the rate requirements of video applications, and automatically adjusting the encoding behavior and code rate of video applications according to the available bandwidth real-timely measured, thus providing more optimized video transmission quality than non-autonomic system.
