Mobile nodes in the integrated network of infrastructure networks and mobile ad hoc networks need an efficient registration mechanism since they register with Internet gateway via wireless multiple hops. Tree-based mobility management is highly dependable in that mobile nodes register with Internet gateway along tree paths from itself up to a gateway without using flooding. In this paper, we introduce a new method using a virtual multi-parent tree in which a node maintains multiple parents whenever possible. A mobile node can still retain its upstream path to a gateway even though it loses connectivity to one of its parents. The new scheme is evaluated against the tree-based method and the other traditional methods - proactive, reactive, and hybrid by resorting to simulation. The result shows that the new method outperforms the other ones and also is very robust against the change of topology.
