Abstract
Mobile IPv6 will be an integral part of the next
generation Internet protocol. The importance of mobility in
the Internet gets keep on increasing. Current specification
of Mobile IPv6 does not provide proper support for
reliability in the mobile network and there are other
problems associated with it. This paper proposes “Virtual
Private Network (VPN) based Home Agent Reliability
Protocol (VHAHA)” as a complete system architecture and
extension to Mobile IPv6 that supports reliability and offers
solutions to other related problems. The key features of this
protocol over other protocols are: better survivability,
transparent failure detection and recovery, reduced
complexity of the system and workload, secure data
transfer and improved overall performance.
