Suggests a new data structure for location management in mobile networks. The data structure is based on the tree location database structure. The authors suggest replacing the root and some of the higher levels of the tree with another structure that balances the average load of search requests. For this modification they use a set-ary butterfly network, which is a generalization of the well-known k-ary butterfly. They also suggest modifying the lowest level of the tree in order to reflect neighboring geographical regions more accurately and to support simple location data management. The modification of the lowest level also supports simple handoffs. The update of the proposed location database ensures correct location data following any number of transient faults that corrupt the location database information and thus is self-stabilizing Copyright 2009 IEEE - All Rights Reserved.
