Abstract

With the development of wireless network technologies, mobile users may use various networks easily and expect more advanced services. On the other hand, it may bring on some problems with network resource management that should lead the service provider to improve the current service quality and manage the network resource efficiently. This paper proposes the optimized radio resource management (RRM) scheme that integrates the Grey Relational Analysis (GRA) and game theory. The first applies the GRA to determine the Grey Relation Coefficient (GRC) factors that represent the network preference, and the network provider then selects the requested service that provide maximum payoff through Nash Equilibrium. Six requested services that have one application service among four different types of service classes were considered and the game was played repeatedly. In WiMAX, WLAN 1 and WLAN 2 game, the maximum payoff of each players was 93, 90.6 and 92.8 respectively. The experimental results show that every requested service can be selected by the network provider. Consequently, the proposed radio resource management mechanism is more effective in heterogeneous wireless networks.

무선 네트워크기술의 발전으로 사용자들은 다양한 네트워크를 쉽게 사용하며 다양한 서비스를 이용할 수 있지만, 서비스 제공자들은 서비스의 질을 개선하고 네트워크 자원을 효율적으로 관리하여야 한다. 본 논문에서는 그레이 관계 분석(GRA)과 게임이론을 결합하여 효율 무선자원관리(RRM) 방안을 제시한다. 첫 번째 단계에서, GRA 방법을 이용하여 네트워크 선호도를 나타내는 GRC를 구하고, 두 번째 단계에서는 내쉬 균형점을 찾아 네트워크 제공자에게 최대 보상을 제공하는 서비스를 선택한다. 한 개의 WiMAX와 2개의 WLAN이 공존하는 이종 무선 환경에서, 4개의 응용서비스중 하나를 요청하는 서비스들을 처리하기 위해 게임은 반복적으로 수행하였다. 시뮬레이션 결과, WiMAX, WLAN 1과 WLAN 2의 게임에서, 각 경기자들은 각각 93, 90.6과 92.8로 최대 보수를 얻는 것을 알 수 있었다. 결과적으로 제안된 시스템은 이종 네트워크에서 사용자 서비스 요청이 있을 때, 네트워크 운용자의 보수를 최대로 할 수 있는 효과적인 자원관리 방법임을 알 수 있었다.
