Simultaneous mobility in MIPv6

Abstract

Mobile IP for IPv6 (MIPv6) includes a procedure for route optimization, which allows packets from the correspondent host to go directly to the mobile host. However, the way route optimization is implemented makes it vulnerable to problems with simultaneous mobility, which can occur when two mobile hosts are communicating with each other. In this paper, we suggest ways to change MIPv6 to reduce its vulnerability to the simultaneous mobility problem.
