Cross-Layer Anticipation of Resource Allocation for Multimedia Applications Based on SIP Signaling over DVB-RCS Satellite System

This paper introduces a cross-layer approach for improving QoS guaranties to interactive multimedia applications over an efficient satellite access assignment scheme (on-demand). It particularly focuses on the communication opening which represents the weakness of on-demand capacity allocation in the satellite context (due to significant delays). It finally presents experimental results of the various proposed enhancements.
