With the Internet host mobility solutions, the packet routing paths depend decisively on the “somewhere” which holds the information for a mobile host’s physical locator. If location updates are taken place without considering the routing effectiveness, it would result in a performance burden to the mobility support system as a whole. In this paper, we firstly review two location update mechanisms optimizing the routing paths for a moving host. One scheme makes use of the locality properties of host moving and calling pattern, and the other utilizes the location notification to source host whenever a new location information is expected to improve packet routing. Using a network simulator, these schemes were evaluated in terms of location overhead and routing effectiveness. Then, a rationale for certain features of location and routing optimization design was provided based on the simulation results.
