Bandwidth Allocation Scheme over Wireless Video Communication

In this study, in order to fairly and efficiently allocate the bandwidth in wireless multiuser multimedia communication, a rate allocation framework based on balance of supply and demand in micro-economics was proposed. The proposed framework take a full consideration of the telecom operators profit and define the bid function as the unit price of frequency spectrum when the users and telecom operators have the maximum profits at the same time. Moreover a user priority factor for different users has be considered. The contents of different videos when proposing the utility functions to reflect fairness has be token consideration. Different users gamble mutually to achieve maximum profits. Simulation results demonstrate that the game theory in this paper have a Nash equilibrium point, the user priority factor plays a role when allocation bandwidth between different user grades. Also a better transmission quality compare with tradition rate allocation method has been showed in the simulation.
