Adaptive reservation in WLAN networks under smooth random mobility model

This papers presents a novel technique to predict the number of WLAN cells visited by a mobile host during its call holding time. A two-dimensional wireless mobility model called Smooth Random Mobility Model (SRMM) has been considered, because it makes the movement of users smoother and more realistic than well-known in literature random mobility models. A prediction technique based both on the analysis of Cell Stay Time and on the direction probabilities of hand-in and hand-out events of mobile nodes from wireless cells is outlined, as a method for QoS guarantees, lower bandwidth wastage and higher system utilisation. An integrated architecture able to make active and passive reservations has been applied as possible application of the proposed approach. Simulation results have been carried out and an interesting bandwidth management usage has been observed.
