QoS Management for Mobile Users

Abstract: The major challenge in wireless environment is the provision of quality of service (QoS) guarantees that different applications demand considering the highly dynamic nature of these environments. In this context, provide to mobile users the QoS required is a very important field of research. Our approach to improve the QoS in the wireless network is based on the user mobility profile, after the determination of this profile, an advance resources reservation is made for the mobile terminal solely in the locations where it can visit. The determination of this location is made after an observation phase during which the user is new and his mobility profile is unknown for the system. During the observation phase, the system can't make advance resources reservation for the user. In this case, we use Agent technology in order to improve the QoS for this user
