Abstract
With rapid advances in wireless communication technologies and with the advent of the smaller and high-performance mobile handsets nowadays, many researches are actively performed for providing seamless communications while mobile nodes are roaming around. As real-time application programs are more prevalent, it is very important to manage mobility of mobile nodes efficiently. In this paper, we propose a localized mobility support scheme that is based on the Mobile IPv6 by IETF. The proposed scheme enhances functionalities in mobile nodes and only uses signaling messages of Mobile IPv6. The performance of the proposed scheme is evaluated through analytical model and simulations. According to the results of the evaluation, the proposed scheme provides better performance than Mobile IPv6 in terms of packet losses and TCP throughput by localizing the binding update messages inside the foreign domain during handoffs and reducing binding update time.
