Analysis of Client-Based and Network-Based Mobility Protocols

With the development of ubiquitous Internet and user's devices, seamless access property becomes essential in the world today, which motivates the new notion of mobility capability. Several protocols have been designed in order to bring seamless access to users. Several solutions have been proposed, which can be classified as client-based mobility and network-based mobility solutions. Client-based mobility solutions such as (Client) Mobile IP, Hierarchical Mobile IP, HAWAII and Cellular IP depend on Mobile Node to initiate the mobility registration, whereas network-based mobility solutions such as Intra-domain Multicast-base Mobility and Proxy Mobile IP initiate the registration from network entities. Proxy Mobile IP delivers fast handoff mobility service to all wireless-capable devices, and also provides network administrator full control over the mobility procedures. In this paper we analyze client and network based mobility protocols providing pros and cons of existing solutions. We have developed and built test beds and simulations using WLAN, WIMAX and 3G networks to evaluate performance of mobility solutions.
