Analysis of a movable boundary random/DAMA accessing technique for future integrated services satellites

In this paper, we pursue a performance analysis of a movable boundary accessing technique for a future integrated services multibeam satellite. We consider the integration of four user services video, voice, file data and interactive data using both random access and demand assigned access along with a moving boundary policy, to ensure that a maximum utilization of the frame capacity is achieved. It is shown that the potential user population is substantially increased with the use of a moving boundary policy and that minimal overhead is required to accommodate tens of thousands of users in the uplink spotbeam
