Adaptive Location Management Strategy Combining Distance-Based Update and Sectional Paging Techniques
In this paper, we develop a new adaptive scheme in which an optimal distance-based update threshold is selected not only as a function of the call-to-mobility ratio, but also as a transitional directivity index ω; a new parameter introduced to give some measures of the mobile’s traveling patterns. It is assumed that when ω > 1, the mobile has a greater tendency of roaming “outwards” and hence a higher probability of transition to the next ring during each movement. As a result, the defined threshold will be reached sooner incurring more update costs. A corresponding sectional paging scheme is therefore proposed to predict mobile’s likelihood of residency utilizing the information given by the estimated ω. Provided that the prediction of location probability is reliable, a movement pattern with increasing directivity will justify having increased update thresholds without incurring additional paging costs. As far as the mobility
