초록

인도어 무선 통신 시스템에서 무선 네트워크의 신뢰성 보장을 위하여, 갑작스런 네트워크 결함 문제의 발생을 신속하게 해결해야 한다. 본 논문에서는, 사용자들에게 끊김없는 연결성 제공을 위하여 적응적 자원관리 (ARM: Adaptive Resource Management) 기법을 제안한다. 시스템 용량 및 사용자 공평성을 동시에 고려하여, ARM 기법에서는 적응적으로 힐링 서브채널 세트를 결정하고, non-convex 최적화 문제를 기반으로 서브채널과 파워를 반복적으로 할당한다. 시뮬레이션을 통하여 평균 셀 용량과 사용자 공평성 관점에서 제안하는 기법의 우수성을 증명한다.

To provide network reliability in indoor wireless communication systems, we should resolve the problem of unexpected network failure rapidly. In this paper, we propose an adaptive resource management (ARM) scheme to support seamless connectivity to users. In consideration of system throughput and user fairness simultaneously, the ARM scheme adaptively determines the set of healing channels, and performs scheduling and power allocation iteratively based on a constrained non-convex optimization technique. Through intensive simulations, we demonstrate the superior performance results of the proposed ARM scheme in terms of the average cell capacity and user fairness.
