—In this paper we study a constraint-based routing strategy using label switching in a multi-layered hierarchical satellite constellation such as Transformational Communications Architecture. Both quality (Bit Error Rate on free space optical and radio inter-satellite links) and bandwidth availability on a satellite link are taken into account when setting(More)
In this paper, we study the role of noisy feedback in compound Gaussian multiple access channels, where both the set of active users and their respective channels are unknown a priori. The system is modeled as a special form of two-way network, where transmitters and receivers can interact with each other to improve the overall communication efficiency, but(More)
