With a current basic Network Mobility (NEMO) Support, all the communications to and from a node in a mobile network must be able to go through the bi-directional tunnel established between the Mobile Router and its Home Agent when the mobile network is away from the home. One of the issues in designing mobile network with MR-HA bi-directional tunnel is to solve the route optimization problem in the nested mobile networks. Since the aggregated hierarchy of mobile networks becomes a single nested mobile network, in order to forward packets to the nested mobile network nodes, multiple levels of bi-directional nested tunnels are required. We propose a hierarchical mechanism that allows direct packet tunneling between HA and MR and allows localized mobility management for MR.
