Celandroni N., Davoli F., Ferro E., Gotta A., Secchi R. Toward a complete control framework for adaptive capacity allocation in mobile DVB-RCS. In: 13th Ka and Broadband Communications Conference (Torino, Italy, 24-26 September 2007). Proceedings, pp. 607 - 613. IIC, 2007.
The general problem of controlling and optimizing access and bandwidth sharing among different applications in mobile DVB-RCS is approached in the paper. After sketching the general system architecture, the paper deals explicitly with the dynamic assignment of bandwidth to elastic (TCP) traffic on the uplink. Two different techniques, based on random and deterministic access, respectively, are compared, in terms of bandwidth usage and average completion time per connection, when conveying acknowledgment traffic from mobile clients on the return channel. Simulation analysis of file transfers under a realistic channel model shows that the convenience of using a technique or the other ultimately depends on the file size.
