Abstract

In this paper, we propose an access point selection method for mobile users in LTE-femtocell system. In wireless communication system, users want to receive good data service. In LTE-femtocell system, if users move a little, users can experience different data service. The proposed access point selection method help that if users move a little, users obtain the high capacity and that user selects access point that other user have not selected much and so obtains higher data service. We simulated in order to prove performance of the proposed access point selection metod. Simulation results show that in a situation that users are concentrated in order to obtain better data service users are seen scattered look. As a result, we confirm that the proposed access point selection method provides good data service to users.

본 논문에서는 LTE-Femtocell 환경에서 최적의 사용자 Capacity, Load, Distance를 위한 게임이론 기반의 액세스 포인트 선택기법을 분석하고 알고리즘을 제안한다. 통신 환경에서 사용자들은 더 좋은 데이터 서비스를 받기를 원한다. LTE-Femtocell 환경에서 사용자들은 적은 이동거리로 이전위치와는 다른 데이터 서비스를 경험할 수 있다. 제안하는 액세스 포인트 선택 기법은 사용자가 적은 이동을 통하여 높은 Capacity를 획득하며 다른 사용자들이 적게 선택한 액세스 포인트를 선택하여 더 좋은 데이터 서비스를 얻을 수 있도록 도와준다. 제안하는 액세스 포인트 선택기법의 효과를 입증하기 위하여 컴퓨터 모의실험을 하였다. 모의실험 결과로 사용자가 밀집되어 있는 상황에서 사용자들은 더 좋은 데이터 서비스를 위하여 흩어지는 모습을 보이며 이 결과로 제안하는 액세스 포인트 선택 기법이 사용자들에게 더 좋은 데이터 서비스를 제공하는 것을 확인하였다.
