Utility Maximized Two-level Game Theoretic Approach for Bandwidth Allocation in Heterogeneous Radio Access Networks ABSTRACT To solve the optimal bandwidth allocation problem in heterogeneous radio access networks (HRANs), a two-level game-theoretic approach is proposed to maximize the utility of network providers and users by considering the network resource distributions and service demands. EXISTING SYSTEM: Driven by the development of exponential surge of mobile data traffic and various services in recent years, wireless cellular network is undergoing an indispensable transformation by enhancing the traffic volume density, peak data rate and user experienced data rate with the purpose of improving the spectrum efficiency, energy efficiency and cost efficiency in 5G networks. Featured by different transmit power and data rate capabilities, H-RANs can support various quality of services (QoS) by different radio access technologies (RATs) with cell coverage types ranging from microcell to femtocell . Moreover, considering the complimentary capabilities of supporting various services by different networks, the convergence of HRANs has become one of the undeniable solutions to meet demands of spectrum efficiency and capacity improvement in 5G networks DISADVANTAGES: Complexity and cost for the periodical information exchange in centralized control scheme high cost The resource allocation problem PROPOSED SYSTEM: Further Details Contact: A Vinay 9030333433, 08772261612, 9014123891 #301, 303 & 304, 3rd Floor, AVR Buildings, Opp to SV Music College, Balaji Colony, Tirupati - 515702 Email: [email protected] | www.takeoffprojects. We have proposed a game-theoretic approach for bandwidth allocation in H-RANs, consisting of both area level game and traffic-level game. In the area-level game, the optimal bandwidth allocation is established and formulated by the Nash equilibrium to make network providers decide on the bandwidth allocation to each service area. Furthermore, the traffic-level game is proposed for the bandwidth allocation and pricing in a certain service area using an iterative algorithm to achieve the Stackelberg equilibrium. Simulation results verify that proposed gametheoretic approach can maximize the network utility and user utility efficiently and significantly from network providers and users perspectives. Besides, the adjustment of bandwidth allocation to different service areas by network providers can avoid the network congestion and overflow in a service area in order to serve a relatively large number of users. In the traffic-level, users can achieve the high utility and the fairness based on Stackelberg game and proposed Match-Degree algorithm. Results also verify that user’s service experiences are also improved by considering about the competition and suitability between networks and traffics.
