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 is not suitable for frequent mobile handovers due to user's high mobility. In this paper, the authors propose HiSIGMA, a hierarchical location management scheme for transport layer mobility schemes. They used an analytical model to evaluate HiSIGMA using signaling cost as the performance measure, followed by comparison of the signaling cost of HiSIGMA and hierarchical mobile IPv6 (an enhancement of mobile IP) and existing transport layer mobility solutions.
