Dominating set-based location management architecture for mobile IP networks

摘要

Mobile IPv4 and Mobile IPv6 were proposed to extend the IP protocol to support mobility. They use two IP addresses: a home network address that is used as a permanent identification address, and a care-of-address acquired at the foreign network and used for routing and data delivery. Hosts that want to communicate with a mobile node send packets to the MN's home network which forwards them to the MN's current network. In Mobile IP, the MN should keep updating its home network about its current location. Every time a MN is called, the home network is queried. Signaling traffic resulting from the location update and packet delivery procedures has a significant impact on the performance of the Mobile IP networks. In this paper, we propose a new location management architecture that is based on the dominating set theory and aims at reducing the cost of location update and data delivery procedures. The proposed architecture is compared with the MIPv6, Hierarchical MIPv6 and Localized Mobility Management for MIPv6. Obtained results are very promising.
