BiSSL Ph.D. student Alexander Duffy will be presenting his research at the annual Conference on Systems Engineering Research (CSER) on March 25-27, 2024 in Tucson, AZ. His paper, titled “Satellite Network Architecture Performance: Setting the Stage for Bio-Inspired Network Design,” covers:

Abstract: Satellite networks, here defined as groups of artificial satellites where the satellites are interconnected by communications links, are increasing in size, number, and criticality. As humanity’s reliance on these networks grows, so too does the need for these networks to be resistant against and quickly recover from disturbances – that is, they need to be resilient. Prior work has found that human networks such as supply chains, water distribution networks, and power grids can improve their resilience by mimicking biological food webs in their design. This paper begins an investigation into whether satellite networks can also benefit from this bio-inspired system approach. The performance of five hypothetical-realistic satellite network case studies is quantified here using global instantaneous coverage, architectural accuracy, and in-network latency. These performance attributes are then compared to the architectural characteristics of biological food webs using Ecological Network Analysis (ENA) metrics, relating species and their predator-prey interactions in a food web to interactions between satellites in a satellite network. The findings suggest that the bio-inspired route holds promise for improving both the performance and resilience of these critical space networks.
