Abstract

By using wireless terminal, the number of users who wish to use the multimedia service like the Internet as well as Short Message Services and voice service has increased dramatically over the last years. We propose the method that improves Mobile IPv4 (MIPv4) Regional Registration in wireless mobile networks to decrease traffic's transmission delay and message generation compared with an existing method We design the scheme in MIPv4 environments that a packet do not pass through the home agent transmitted from correspondent node to mobile node, if a mobile node moves to other mobility agent. Simulation results show that the proposed method significantly reduces the expenses for registration and delivering packet.

무선 단말기를 이용하여 단순한 문장 및 음성 전송뿐만 아니라 인터넷과 같은 멀티미디어 서비스를 이용하고자 하는 사용자가 증가하고 있다. 본 논문에서는 무선 이동 망에서 Mobile IPv4 지역 위치등록(Regional Registration)을 개선하여 트래픽의 전송 지연과 메시지 발생양을 기존의 방법에 비해 낮출 수 있는 방안을 제안한다. 제안하는 방법은 CN으로부터 전송되는 패킷을 HA를 경유하지 않고 MN이 위치한 지역으로 전달하도록 한다. 본 논문에서는 각 방법에 대해 메시지 발생양과 패킷의 지연시간과의 관계를 보이고, 개선된 MIPv4 지역 위치등록을 이용하여 이를 최소화한다. 본 논문에서 제안하는 방법을 위치 등록 비용과 메시지전송 비용에 대해 기존의 방법과 비교하여 본 논문에서 제안하는 방법이 우수하다는 것을 입증한다.
