Abstract

The configuration of hierarchical wireless networks is provided to support diverse network environments. In the base station, two system state can be basically considered for the operation management so that the state transition may be occurred between active and sleep modes. Hence, to reduce energy consumption the system operation management of the low power should be considered to the base station system. In this paper we consider the analytical model of Discontinuous Reception (DRX) to investigate the system management. We provide the analysis scheme of base station system by the DRX model, and the low power factor would be investigated for the energy consumption. We also use the finite-state Markov system model that in a system state period the wireless resource request and the operation of service call arrival interval is considered to numerically analyze the performance of energy saving operations of base station.

무선 네트워크의 계층적 구성은 다양한 네트워크 환경을 지원하기 위해 제공된다. 기지국에서는 두 가지 시스템 상태가 기본적으로 고려될 수 있으며, 이에 대해 액티브와 슬립 모드 사이에서 상태 전이가 발생할 수 있다. 그러므로 에너지 사용을 줄이기 위하여 저전력의 시스템 운영 관리가 기지국 시스템에 고려되어야 한다. 따라서 본 논문에서는 시스템 관리를 다루기 위해 Discontinuous Reception (DRX) 분석 모델을 고려한다. DRX 모델을 통하여 기지국 시스템의 운영에 대한 분석 방안을 제시하며 에너지 소비를 위한 저전력 강도를 살펴본다. 또한 시스템 상태에서 기지국의 저전력 소모에 대한 성능을 분석하기 위해 무선 자원 요구와 서비스 호 도착의 운영이 고려되며, 이를 위하여 유한 마르코프 시스템 모델을 사용하였다.
