Potential Game Models for Efficient Resource Allocation in Wireless Networks

With increasing demand for data transfer requirements on wireless networks, spectrum became a scarce resource due to inefficient allocation and management. Recent research efforts diverted the problem towards dynamic spectrum access models for effective utilization of the unused or idled spectrum. The models include overlay/underlay techniques by designing the framework to improve the spectrum efficiently by using business and game theory models. Surveying of these models concludes that the key component for efficient utilization of the unused spectrum is the detection of the unused spectrum at any given time. Further, we found that by allocating the unused spectrum using appropriate techniques (business, game, and hybrid models) will produce better results. Among these models, the game models were identified as one of the powerful mathematical tools to detect and allocate the unused spectrum. In this paper, we first discussed the role of game models in wireless communications, player‟s strategy selection for better utility, and then proposed a correlated equilibrium algorithm for efficient allocation of spectrum. The simulations conclude that the mixed strategies are better than the pure strategies in resource allocation.
