Performance Study of Hierarchical MIPv6 with Dynamic MAP Grouping

Abstract

In this paper we extend the concept of abstract MAP (AMAP) node proposed in [6] so that the grouping of MAP nodes can be dynamically configured. As the higher MAP has wider coverage and may accommodate more mobile nodes, the issue of dynamic grouping is initiated by the higher MAP. And whether the grouping is allowed or not depends on the load condition of MAP nodes. In addition, for a mobile node, the dwelling time in an AR is also refined so that the mobile node can select a more appropriate MAP. Our simulation results show that the proposed scheme can effectively reduce the number of local binding updates and the AMAP can achieve the load balance among MAP nodes.
