A Performance Evaluation of IPv6-Based Network Mobility Management

An entire network may move as a unit and change its point of attachment to the Internet dynamically. To support this kind of network mobility, a network mobility basic support protocol for IPv6 (NEMOv6) has been proposed by IETF. This paper analyzes the characteristics of IPv6-based network mobility management, and simulates handoff performance of a mobile router (MR) with a subnet, including one or more mobile nodes (MN) which move in various scenarios. Based on the simulation results, we demonstrate the impact of average moving speed rate and average data transmission rate to the performance of mobile network. Moreover, a Linux OS based network mobility experiment platform was established to evaluate the practical handoff performance of the MR using FTP service. Lastly, future work of network mobility management is proposed.
