Abstract

Proxy Mobile IPv6 (PMIPv6) is a network-based localized mobility support in an IP network. The main advantage of using PMIPv6 is the freeing up of the mobile host when undertaking any mobility-related activity, thereby saving its resources. The mobile access gateway (MAG), however, incurs a high signaling cost for updating the location of a mobile node to the remote local mobility anchor (LMA) if it moves frequently. As it may also cause excessive signaling traffic and high traffic load on LMA, in this paper, a novel LMA selection scheme for load control in PMIPv6 networks is proposed. In the proposed scheme, the AAA server selects the most suitable LMA based on the load information received from the LMAs. Moreover, the LMA performs admission control based on the number of current mobile nodes registered to the LMA. Therefore, the proposed scheme achieves actual load balancing among the LMAs. The cost analysis using the Markov chain presented in this paper shows that the proposed scheme can achieve a performance superior to that of the PMIPv6 scheme
