Konferensbidrag (refereegranskat)abstract
- TLMM, a three level mobility model for IP-based mobility management has been recently proposed as an architecture for managing global mobility in an IP-based network. This paper evaluates the performance of TLMM's Quality of Service (QoS) framework using a combination of DiffServ and Int-Serv architectures with the concept of Bandwidth Broker for admission control and resource reservation for different service classes. The most important contribution in this paper is a dynamic handoff policy using the concept of Boundary Location Area, for performing location updates for inter-domain roaming of mobile nodes, which helps in maintaining proper QoS. The performance evaluation of the proposed protocol is provided by simulation results using Network Simulator (ns-2).

Tidskriftsartikel (refereegranskat)abstract
- This article presents an overview of a set of IP-based mobility protocols - Mobile IP, HAWAII, Cellular IP, Hierarchical MIP, TeleMIP, Dynamic Mobility Agent, and Terminal Independent MIP - that will play an important role in the forthcoming convergence of IP and legacy wireless networks. A comparative analysis with respect to system parameters such as location update, handoff latency and signaling overhead exposes their ability in managing micro/macro/global-level mobility. We use this observation to relate their features against a number of key design issues identified for seamless IP-based mobility as envisioned for future 4G networks.
