Improved Burst Target Demand Assignment Multiple Access (BTDAMA) for GEO Satellite Networks

This paper examines the relative performances of the BTDAMA (Burst Target Demand Assignment Multiple Access) schemes with different demand assignment strategies. A new satellite multiple access scheme employing hybrid demand assignment strategy (BTDAMA-HD) is proposed which combines the burst target demand assignment strategy of the BTDAMA schemes with the packets reserved demand assignment strategy of the variable rate DAMA schemes. The delay performances of BTDAMA-PD (pure demand assignment) and BTDAMA-HD were compared by computer simulation under Pareto ON/OFF traffic source. The results demonstrate that BTDAMA-HD can offer better delay and delay jitter performance over GEO satellite channel.
