Abstract
IETF's Mobile IP protocol allows Mobile Node(MN) to keep connection to Correspondent Node(CN) no matter what the MN changes its point of attachment to the Internet. However, the protocol incurs triangle routing problem, because all packets for the MN are routed through its Home Agent(HA). Route optimization mechanism is proposed by IETF in order to resolve triangle routing problem, but it requires that any node in the Internet should also implement route optimization mechanism. In this paper, we propose a new route optimization algorithm. With the algorithm, routers between HA and CN are considered as Intermediate Agent(IA), and packets transmitted by CN are not forwarded to HA but intercepted by IA and tunneled to MN directly.
