Dynamic mobility tracking for wireless personal communication networks

A dynamic mobility tracking scheme is developed to minimize the cost of mobility tracking by optimally partitioning the service area into location registration (LR) areas on a per-user basis. This cost is affected by the mobility and call pattern of the individual subscriber, as well as the size and the orientation of the LR area. A more realistic mobility model is proposed in which we take not only the mobility behavior of individual subscriber but also the street layout into consideration. Based on this model, a transient Markov process is developed to analyze the tracking cost
