Performance evaluation of host-based mobility management schemes in the internet

Abstract

The literature lacks theoretical and practical evaluations of Distributed Mobility Management (DMM) schemes which aim to mitigate disadvantages of conventional centralized schemes such as a single point of failure, congestion in home network, and limited scalability. This paper selects Global HAHA, Migrating HA, and Distributed Mobile IP (DMIP) as representative host-based decentralized Internet Mobility Management (MM) schemes, and probes their control and data planes against Mobile IP (MIP) and MIP with Return Routability procedure (MIPRR), using real Autonomous System (AS) level topology data of the Internet. By using different combinations of MM Agent (MMA) placements, random sessions are investigated for host mobility in terms of the total number of hops and the AS load. Comparison of generic results shows that DMIP and Migrating HA outperform the legacy schemes. Further, DMIP overcomes consistency maintenance and scalability problems seen in Migrating HA, maintaining much similar performance, while achieving reliability eliminating an expensive controlling overhead as in MIPRR.
