Network Mobility in MIPv6 Considering Arrival Time

Abstract

Mobile IPv6 represents a global solution, providing mobility management for a wide variety of radio technologies, devices, and applications. In particular, Network Mobility basic support protocol is the one of fundamental solutions in MIPv6 which reduces the number of binding update messages issued from mobile network nodes except mobile routers. That is, it never reduces the number of binding update messages which mobile router issues. Significant research results relating to Network Mobility have been reported over last several years. However, practical and common issues exist within the technology; specification of Binding Update Lifetime has a substantial impact the system performance. The binding update message should be delivered periodically for the purpose of user location notification and binding authorization. If the lifetime is too short, the traffic load resulting from the messages may be significant. In addition, issues related to authorization can be problematic. In this paper, therefore, Network Mobility considering arrival time is devised to solve the binding update explosion of mobile routers without security problem in Network Mobility.
