Abstract

Introduction. Satellite is often used as an access network in convergent multimedia communications, where multimedia and real-time services are supported by return channels. Demand assigned multiple access (DAMA) applied for efficient assignation of limited resource of satellite return channel. On-board signal processing gives a lot of functional benefits for satellite systems and can be used as possibility to implement DAMA mechanism on satellite.
Theory part. Simplified algorithm of dynamic resource allocation presented which is equivalent for both inside Network Control Center (NCC) and on-board implementations of DAMA. Realization of algorithm is based on information about transmission buffers load of each terminal station.
Experimental part. Imitation model of return satellite channel with DAMA was developed and tested. Average buffers load and performance of channel level were chosen as characteristics to compare systems with NCC and on-board DAMA implementation. These characteristics were measured for different available return channel capacity.
Conclusions. Experiments showed significant average buffer load reduction and 5-6% performance gain for on-board implemented DAMA model comparing to traditional realization. However, model of DAMA mechanism has drawbacks (bit representation of data, physical layer constraints are not considered for resource allocation granularity) and it should be improved for more precise results.
