Virtual LAN supporting quality of service in wireless ATM networks

This paper introduces virtual LAN (VLAN) services using ATM LAN emulation technology which operates on a client/server model. One of the attractive features of the VLAN is the capability to group users into a broadcast domain. The focus of this paper is the issue of supporting quality of service to mobiles in a wireless ATM network. An architecture based on emulated LAN is proposed which can efficiently provide the required bandwidth of mobiles as they migrate between cells.
