초록

본 논문에서는 자연계에 존재하는 동기화 현상에 착안하여 무선 네트워크를 위한 자율적 부하균형 기법을 제안한다. 이를 위해 본 논문에서는 무선 접속 서비스를 제공하는 셀 사이의 부하균형 문제를 자연계 동기화 현상을 이용하여 모델링 한 후 각 셀들이 이웃 셀과의 부하 차이에 따라 자율적으로 부하를 분배하기 위한 알고리즘을 설계한다. 모의실험을 통해 제안 기법을 이용하여 각 셀들이 자신의 지역적 정보만을 이용하여 자율적으로 부하 분배 여부를 결정하더라도 셀 간 부하균형을 이룰 수 있다는 것을 검증하였다.

Inspired by the synchronization phenomena observed in the Nature, we propose an autonomous load balancing method for a wireless network. We model the load balancing problem of cells providing wireless access services as a synchronization problem in the Nature and design an algorithm for each cell to distribute loads in a self-determining way based on the load differences among its neighbor cells. Through simulations, we verify the feasibility of the proposed method in that cell loads can be balanced efficiently eve if cells make decision autonomously using their local information.
