Abstract

In this paper, we propose that a FDL(Freeze DeadLine) Algorithm to solve handover problems in heterogeneous wireless networks. Many previous studies concentrated on low level layer to solve handover problems. In this paper, however, we concentrate on high level handover problems such as network layer and transport layer. We analyze handover's problems of transport layer in Heterogeneous wireless network, propose the FLD algorithm for better performance than others studies. The Proposed method is analyzed by theoretical frames and we verify that the propose method using the NS-2(Network Simulation - 2).

본 논문에서는 이기종 무선망 네트워크 환경에서 핸드오버가 발생할 때 생기는 문제점을 해결하기 위하여 FDL(Freeze DeadLine) 알고리즘을 제안하였다. 많은 선행연구들은 하위 계층의 정보를 이용하여 핸드오버 과정에서 생기는 문제를 해결하기 집중하였다. 하지만 본 논문에서는 핸드오버 과정에서 생기는 상위계층에 대한 문제를 다루고 있다. 본 논문에서는 핸드오버가 발생할 때 상위 계층인 전송계층에서 생기는 문제점을 분석하고, 성능을 개선하기 위하여 FDL알고리즘을 제안하였다. FDL알고리즘을 이용하여 기존에 제안되었던 기법보다 더 나은 성능을 보임을 이론적으로 분석하였고, 이를 NS-2(Network Simulator -2)를 통해 성능 평가 하였다.
