Distance-based approach is most efficient among the three strategies, namely time-based, zone-based, and distance based, used for location management of mobile hosts (MHs) in a cellular PCN. In this work, we made one important observation about the optimum distance and then proposed a new updating strategy. When the MHs are static, depending on where they had last updated, the paging cost and delay could be high for the incoming calls during the static period. To avoid this situation we use the variance of paging delay as a measure of the mobility of the host. We have shown that using this parameter as an indicator for updating, we can reduce the paging cost to a great extent. The improvement is shown by simulation.
