Abstract

In this paper, we propose a method that wireless mobile nodes can obtain high throughput in heterogeneous wireless networks using multiple connections and it has low packet loses under handover situation. Currently, a mobile node exchanges data with server for one network connection. The proposed method can use high throughput because it doesn't only use one network(WLAN, 3G, etc.) but also use multiple wireless networks. When mobile nodes move to area to use multiple connection, mobile nodes request heterogeneous wireless networks using multiple connections message from the server and the server transmit packets using multiple connections. Also, this method doesn't disconnect previous networks, so packets losses are decreased. Using the NS-2 simulation, we verify that the propose method enhances throughput.

본 논문에서는 무선 이동 단말이 이기종 망의 다중 연결을 통해 높은 대역폭을 이용하고 또한 이기종 망의 동시사용을 통해 손실 패킷을 감소시킬 수 있는 기법을 제안한다. 현재의 이동 단말은 하나의 네트워크를 통해 데이터를 전송한다. 하지만 제안하는 기법은 이동 단말이 WLAN과 3G망 등 다수의 망이 존재하는 환경에서 하나의 망을 사용하는 것이 아니라 이기종의 망의 동시 사용을 통해 대역폭을 넓게 사용한다. 이기종 망을 동시에 사용할 수 있는 지역으로 이동 단말이 이동하게 되면 이를 인지한 이동 단말은 서버에 이기종 무선망 동시사용 허용 요청을 하게 되고, 이를 수신한 서버는 다수의 프로토콜 연결을 통해 데이터를 전송하게 된다. 또한 제안하는 기법은 이동 단말이 다른 네트워크로 이동할 때 기존의 망을 끊지 않기 때문에 핸드오버 구간에서 발생하는 패킷 손실이 감소하게 된다. 제안하는 기법을 네트워크 시뮬레이션(NS-2)을 통해 실험하였고, 처리량이 향상되었음을 확인하였다.
