Abstract :
Various tracking strategies for the location of a mobile user in a cellular system have been introduced in literature. Up to now they have been evaluated using simple mobility models that do not take into account the various directions in which users often move. We present a comprehensive study of the distance-based, movement-based and multilayer strategies, from which it emerges that the effectiveness of these techniques depends not only on the call-to-mobility rate, a parameter typically referred to in literature, but also on the directional characteristics of the user mobility model
