Abstract

In this paper, we propose a new dynamic slot assignment algorithm called Neural DSA in order to guarantee the QoS (Quality of Service) of VBR (Variable Bit Rate) traffics and maximize the efficiency of channels in wireless ATM. In the proposed algorithm, the status of terminal buffers and cell generation rate are encoded in signed number on the GFC (Generic Flow Control) field of an ATM cell header and piggybacked (in-band). The number of slots to be assigned to the next frame is adjusted effectively by using the neural networks, which is different from the conventional slot assignment algorithms. Experimental results show that the proposed algorithm lead to the guarantee of QoS such as CLR (Cell Loss Rate) and cell delay as well as the higher utilization of channels. The efficiency of this algorithm is verified by the simulation using the BONeS tool.
