In this paper, we propose a closed-loop structure of intelligent policy system for wireless channels allocation of IA (information appliance). At first, an approximated mathematical model and optimality equations of dynamic programming is defined. Then, the optimal control policy for this model can be computed via the method of successive approximation. Based on this algorithm for computing optimal policy, we design an intelligent system with feedback control to regulate the allocation of limited wireless channels. This intelligent system will continuously detect the status of usage of wireless channels. Once the system parameters deviate the predefined threshold or the prioritized weight for any type of in-coming request needs to be adjusted, the recomputing mechanism will be activated. Then a new optimal control policy is figured out and saved in database for use. Such a feedback control mechanism ensures that the performance of IA will keep near to the optimal level from time to time.ABSTRACT
