Improvement of the Location Update Delay and Packet Transmission of MH Movement on the Mobile IP Network Mobility Management Server

Abstract

IP movement support is based on terminal operation to recognize mobility while moving and maintain a continuous communication session. The main content of the paper is that the proposed HMIPv6 aims to reduce the delay time of location updates because of movement of MH. This paper in order to work out the problem that can cause excessive traffic and long delay, IP address locations are stored in geographically distributed mobility management servers, and when a request comes in, it is proposed to request information from the nearest server. By doing so, performance was improved by utilizing packet transmission through an optimized path. In the proposed method of this paper, if the average interaction CNs increases, the mobility location update cost extends. However, due to the hierarchical structure using the Mobility Management Server, the location update cost () showed an average decrease of 12.8%. As a result, it is shown that the suggested method effectively lessen the cost compared to the existing method despite the high packet forwarding cost and not high mobility location update cost.
