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

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.
ADVANTAGES:

Maximizing the overall utility of network providers.

non cooperative game for bandwidth allocation is proposed

utilizing appropriate network resources
