Abstract

QoS guarantee is a very important issue in wireless communications, when mobile nodes move among different coverage areas. This paper presents a novel 2D reservation scheme for WLAN environments. A general 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. A threshold-based algorithm is presented, trying to take into account the mobility behavior of mobile users, through the analysis of a directional probabilities matrix. Many simulations have been carried out and a performance analysis has been performed, finding a good trade-off between bandwidth utilization and prediction error.
