Distributed QoS awareness in satellite communication network with optimal routing (QuASOR)

Air and space resiliency requires efficient and functioning avionics using a robust and scalable architecture. In satellite communication (SATCOM) networks, each satellite can be treated as a topological node, such that the overall constellation can be represented by a graph matrix (i.e., graph Laplacian or adjacency matrix), and the quality of service (QoS) of each inter-satellite link (ISL) captures the instantaneous well-being of the communication channel. The exact value or condition of the SATCOM network is crucial, if not critical, in dynamic routing and communication management. However, each satellite could only access to QoS information of its adjacent ISLs. The proposed QoS Awareness in Satellite communication network with Optimal Routing (QuASOR) schemes take advantage of the discretized information flow within satellite constellation to balance between situational awareness and communication overhead. Simulations results verified the effectiveness of the QuASOR method for a space scenario.
