TRAFFIC MANAGEMENT IN SMART GATEWAY NETWORKS

The usage of Q/V-band gateway links would increase the capacity of future TLC satellite systems at the expense of heavy propagation impairments. The resulting link outages could be affordable if a smart gateway network was in place to reroute the traffic to the end users through the operational links. The performance assessment and optimization process of such complex systems requires modeling at both network and channel levels. This paper presents a simulation tool based on an enhanced version of the QualNet licensed simulator, which features an advanced channel model and a dedicated traffic management algorithm, and shows its effectivity in a simple case-study under challenging weather conditions.
