  Abstract

In Hierarchical Mobile IPv6 (HMIPv6) networks, the mobility anchor point (MAP) handles binding update (BD) procedures locally to reduce signaling overhead for mobility. However, as the number of mobile nodes (MNs) handled by the MAP Increases, the MAP suffers from the overhead not only to handle signaling traffic but also to process data tunneling traffic Therefore, It IS Important to control the number of MNs serviced by the MAP. m order to mitigate the burden of the MAP We propose an adaptive load control scheme, winch Consists of two sub-algorithms threshold-based admission control algorithm and session-to-mobility ratio (SMR) based replacement algorithm When the number of MNs at a MAP reaches to the full capacity, the MAP replaces an existing MN at the MAP, whose SMR is high, with an MN that Just requests binding update The replaced MN IS redirected to Its home agent We analyze the proposed load control scheme using the Markov chain model m terms of the new MN and the ongoing MN blocking probabilities Numerical results indicate that the above probabilities are lowered significantly compared to the threshold-based admission control alone
