Abstract

To alleviate the problem of sub-optimal routing and multiple encapsulations in nested mobile network, a hierarchical based route optimization scheme (HBRO) is proposed. Root mobile router (MR) works as mobility anchor point (MAP) and transmits packets for the mobile network nodes (MNNs). Following advantages can be achieved with this scheme: 1) correspondent node (CN) transmits packet directly to MAP, bypassing all of the home agents (HA) of MRs; 2) tunnel exists only inside the mobile network. We build an analysis model for for performance evaluation, and the analysis results indicate that packet delivery overhead decreases significantly, and the delivery efficiency is beyond 80 percent when packet size is larger than 200 bytes and network resources are utilized to a great extent.
