✦ Synopsis

To provide high QoS (Quality of Service) with mobile hosts, service managers must ®rst make resource reservations at subsequent locations to which mobile hosts may visit during the lifetime of the connection. In this paper, we propose a mechanism based on Fuzzy Matrices with movement directions and mobility speci®cations to predict the locations that a mobile host will visit. Through the fuzzi®cation, defuzzi®cation, and inference procedures, a resource reservation scheduling was performed. Our study indicates that the proposed strategy may signi®cantly reduce the mean inef®ciency (miss rate) and operating cost at 27 and 32%, respectively, compared with other approaches at the expense of a small blocking rate.
