Abstract

In mobile computing system, user location management is one of the most important issues. Conventional IP paging protocols deliver paging request packets without careful consideration of residence pattern of mobile users. In this paper, we propose quick paging IP scheme utilizing the residence pattern of Mobile Node. Paging the whole paging area might incur huger overhead than paging a few subnets. Since the number of frequently visited locations would be small compared to the number of subnets in whole paging area, we deploy xcast in our scheme. For the performance evaluation, we develop an analytical paging cost model to compare the overall cost of our scheme and the cost of Paging Extensions for Mobile IP scheme. The results indicate that the proposed scheme gains about 47% of improvement at its best.
