In this paper, we enhance the mobility model presented in [1], considering a wider range of the directional movement parameter (*** ). Both random walk and totally directional mobility patterns are modeled. This model is used as an input to study and compare the location management cost of the movement-based strategies [2] and the distance-based scheme as a function of the mobile terminal directional mobility patterns. In [2], each time the mobile terminal revisits the last cell it had contact with the fixed network, its movement-counter is increased with probability p or it is frozen (stopped) with probability q or it is reset with probability r , (p + q + r = 1). We discuss the trade off between the location update cost and the terminal paging cost. The distance-based strategy outperforms all the movement-based schemes. Among all the movement-based mechanisms, the (p ,q ,r ) = (0,0,1) ---reset strategy--- provides the best performance. All studied schemes tend to perform equally as the movement is more directional.
