초록

무선 네트워크에서 서비스 공급자 및 고객을 동시에 만족시키기 위해서는 전력 효율성과 수신기 공평성 보장이 중요하다. 본 논문에서는, 최적화 기법에 기반하여 무선 네트워크의 전력 효율성과 수신기 공평성을 동시에 향상시키는 자원 할당 방안을 제안한다. 제안 방안에서는 채널 상황, 사용되는 전력량, 수신기 별 데이터 전송률을 동시에 고려하여 전력 효율성과 수신기 공평성을 높이는 방향으로 반복적으로 서브채널 및 파워를 할당한다. 시뮬레이션을 통하여 전력 효율성과 수신기 공평성 관점에서 제안하는 기법의 효율성 및 우수성을 증명한다.

In wireless networks, it is important to guarantee the energy efficiency and receiver fairness for satisfying service provider and customer at the same time. In this paper, we propose a resource allocation algorithm which improves energy efficiency as well as receiver fairness based on optimization techniques. In the proposed algorithm, subchannel and power are allocated to receivers iteratively in the consideration of channel state information, amount of dissipated power, and receiver rate, in order to improve energy efficiency and receiver fairness. Through simulation, we show the effectiveness and superiority of the proposed algorithm in terms of energy efficiency and receiver fairness.
