A Distributed Flow Rate Control Algorithm for Networked Agent System with Multiple Coding Rates to Optimize Multimedia Data Transmission.

With the development of wireless technologies, mobile communication applies more and more extensively in the various walks of life. The social network of both fixed andmobile users can be seen as networked agent system. At present, kinds of devices and access network technology are widely used. Different users in this networked agent system may need different coding rates multimedia data due to their heterogeneous demand. This paper proposes a distributed flow rate control algorithmto optimizemultimedia data transmission of the networked agent systemwith the coexisting various coding rates. In this proposed algorithm, transmission path and upload bandwidth of different coding rate data between source node, fixed and mobile nodes are appropriately arranged and controlled. On the one hand, this algorithm can provide user nodes with differentiated coding rate data and corresponding flow rate. On the other hand, it makes the different coding rate data and user nodes networked, which realizes the sharing of upload bandwidth of user nodes which require different coding rate data. The study conducts mathematical modeling on the proposed algorithmandcompares the systemthat adopts theproposedalgorithmwith the existingsystembasedon the simulationexperiment andmathematical analysis. The results show that the system that adopts the proposed algorithmachieves higher upload bandwidth utilization of user nodes and lower upload bandwidth consumption of source node.
