Wireless LANs, each consists of a base station and several remote stations, interconnected by ATM backbone network will be one of the most attractive infrastructures for modern multimedia applications. This paper proposes an efficient traffic scheduling architecture and policy for wireless LANs interconnected by an ATM backbone network. Both time-sensitive and time-insensitive transmission services are furnished and guaranteed. An efficient traffic scheduling policy is designed so that multiple real-time connections can be furnished concurrently with guaranteed quality of service (QoS). For each wireless LAN, network bandwidth not consumed by the time-sensitive traffic is fairly used to serve time-insensitive traffic. Simulation results indicate that the proposed protocol successfully guarantees the QoS requirements of established connections and the bandwidth for time-insensitive traffic can be shared equally among the remote stations.
