WLC35-2: Hierarchical Location Management for Transport Layer Mobility

IP mobility can be handled at different layers of the protocol stack. Mobile IP has been developed to handle mobility of Internet hosts at the network layer. As an alternative solution, a number of transport layer mobility protocols have been proposed. However, the location management schemes used in these transport layer solutions are not suitable for frequent mobile handovers due to user´s high mobility. In this paper, we propose HiSlGMA, a hierarchical location management scheme for transport layer mobility schemes. We used an analytical model to evaluate HiSlGMA using signaling cost as the performance measure, followed by comparison of the signalling cost of HiSlGMA and hierarchical mobile IPv6 (an enhancement of Mobile IP) and existing transport layer mobility solutions.
