A comparison of mobility protocols for quasi-dynamic networks

In this paper, we compare various existing approaches for locating roaming users and providing continuous connectivity in quasi-dynamic networks in which the movement is much more restricted than in ad-hoc networks. However, there are frequent host movements combined with occasional major topology changes (e.g., whole network is changing their point of attachment or getting disconnected). The higher dynamics causes many proposed mobility solutions including basic Mobile IP (which work well in environments limited to host mobility), perform poorly. Based on some qualitative comparisons, we suggest which approaches are the best to handle mobility in quasi-dynamic networks.
