Abstract

Abstract:

A case-based reasoning approach for generating the optimal policy is presented, which can be used for radio resource management and optimization in an autonomous and efficient mode in heterogeneous wireless networks. It searches for the most appropriate reuse policy in the case library by utilizing case retrieval and matching algorithms, and improves the new policy’s efficiency and quality of learning by utilizing the policy reusing algorithm based on the probability of similarity. The approach also introduces the greedy algorithm for generating coping policies when there is no case available. In addition, it updates in real time the policy case library based on learning. Simulation results show that the proposed approach owns efficient online learning ability, and can effectively improve the network blocking rate together with spectrum utility performance. It achieves the autonomous management of radio resources.

Key words: optimal strategy, heterogeneous wireless networks, radio resource management, spectrum utility
