Domain Moblity Management for Wireless Network with Public Key Cryptsystem

Abstract

Mobile IP presents an efficient solution to mobility problem on the Internet. However, if an MH handoffs so frequestly that it needs to register with a distant HA for each handoff which causes high overhead, besides the handoff may be delayed and packet loss aggravated. Hence we propose the Group Foreign Agent management scheme in the foreign domain to alleviate these problem, and all the FAs have the authentication information of the MHs which are sent in advance by other neighboring FAs so that they have the ability to authenticate MHs independently, not through anyone.
