A comparative analysis on signaling cost of mobile IP regional registration with paging support

In this paper, we present a comparison of IP routing in mobile environments. We consider four protocols: mobile IP, mobile IP with paging support, mobile IP regional registration and mobile IP regional registration with paging support. The comparison is done by mathematical modeling and simulation. The comparative metric is signaling costs which are measured by a composition of registration and paging messages. The comparison considers several system parameters such as the number of base stations in the paging area, cell perimeter and mobile node velocity.
