Abstract

The capability of Hierarchical Mobile IP (HMIP) for intra-domain route optimization is impaired when it is combined with Network Mobility (NEMO) technology. Deviations from the optimum path, caused by traffic aggregation in the Mobility Anchor Point (MAP), can be observed within a hierarchical domain. The problem is particularly noticeable in domains that span the mesh network topology. The lack of intra-domain path optimization in multi-level Mobile IP (MIP) leads to inefficient use of network resources. A Proxy Mobility Anchor Point (PMAP) functionality is proposed in domain nodes to enable intra-domain path optimization in multi-level MIP. Numerical evaluation and simulations indicate that this proposal can improve routing efficiency and throughput. The solution can be especially rewarding in network architectures where access network is separated from global network by bottleneck links and where the majority of users accessing the network are mobile routers.
