Abstract
In wireless networks, efficient mobility management is a crucial issue to support mobile users. The Mobile Internet Protocol (MIP) has been proposed to support global mobility in IP networks. Several mobility management strategies have been proposed to reduce signaling traffic related to the registration of Mobile Terminals (MTs) with Home Agents (HAs) whenever they change their Care-of-Addresses (CoAs). They use foreign agent hierarchies (AFs) and FAs of the gateways (GFA) to concentrate the registration processes. For high mobility MTs, Hierarchical MIP (HMIP) and Dynamic HMIP (DHMIP) strategies locate the record in FAs and GFAs, yielding to high mobility signaling. The HMIP Multicast strategy limits the registration processes in the GFAs. For high mobility MTs, it provides slower mobility signaling delay compared to the HMIP and DHMIP approaches. However, it is strategy of resource consumption unless for the frequent mobility MT. Therefore, we propose an analytical model to evaluate the mean delay signal and the average bandwidth per call according to the type of MT mobility. In our analysis, the MHMIP overcomes the strategies of DHMIP and IPM in almost all the cases studied. The main contribution of this work is the analytical model that allows the mobility management to approach the performance evaluation.
