Novel DLC model for VBR QoS enhancement in wireless ATM networks

Several data-link control (DLC) protocol procedures have been proposed in order to provide reliable data transmission over powerless radio links. However, many QoS issues still need to be achieved such as balance between cell transfer delay (CTD) and cell loss rate (CLR), absence of cell delay variation (CDV), and network traffic utilization. The main problem with wireless ATM is how to overcome the unreliability of the wireless link in order to maintain quality of service requirements especially for VBR application. Here, we propose a model that provides QoS support for ATM virtual connections and solves the unreliability problem of the wireless ATM through an efficient DLC protocol for VBR traffic. This model mainly concerns with enhancing QoS to gain error-free wireless transmission and regulating VBR Traffic
