Long-duration UAV missions are limited by battery capacity, which forces agents to leave the formation and jeopardizes mission continuity. We propose a fully decentralized, communication-centric multi-agent system that enables persistent formation flight by allowing UAVs to autonomously replace depleted members and to hand over leadership without any central controller. The approach is implemented in ROS using the ALICA coordination framework and evaluated in Gazebo simulations that demonstrate resilient formation maintenance and seamless leader/follower handovers.

Internet Exchange Points facilitate traffic exchange through Route Servers that use BGP for path selection without considering latency. This paper presents LARS, the first system to enable latency-aware path optimization at IXP route servers. It requires no changes to BGP and no bilateral coordination among members, thus directly enabling latency-aware routing for all IXP members. LARS continuously probes the route-server RIB, annotates routes with RTT-derived BGP communities, and enables members to (i) enforce a configurable latency radius that suppresses high-latency routes and (ii) prefer lower-latency alternatives when multiple paths exist. We evaluate LARS at a very large IXP using a production-level prototype that demonstrates stable latency estimation, effective tail-latency control via selective redistribution, and potential to optimize BGP best paths.

South Africa's frequent electricity outages—both planned and unplanned—not only disrupt daily life but also impact Internet infrastructure in this critical regional connectivity hub. This study analyses the relationship between power outages and Internet resilience by correlating end-user performance metrics, amateur radio activity, and BGP routing data with detailed outage records. We find that network performance degrades only during unplanned outages, revealing heightened vulnerability during unexpected events. Amateur radio activity shows a weak negative correlation with both planned and unplanned outages, while BGP announcement patterns vary, showing both positive and negative correlations depending on the month. These results show how outage types shape connectivity and give us a deeper insight into the resilience of the Internet in South Africa.

Traditional Internet measurements rely heavily on IP-based vantage points to assess large-scale disruptions, overlooking less conventional but informative data sources. This leaves critical gaps in our understanding of how crises affect specific regions and alternative communication systems. Using PSKReporter's amateur radio data, we present two case studies where distinct signals of crisis events were captured, even when IP-based measurements alone may fall short. During the LA wildfires, PSKReporter spots dropped by 36%, with no comparable decline in IP-based data. For Hurricanes Milton and Helene, spot declines appeared several days earlier than IP-based indicators. These insights open new avenues for studying the resilience of diverse infrastructures during emergencies.

Modern websites are complex and fetch content from a multitude of different servers or domains. When measuring the complexity of the modern web, an open question is how content that is fetched from these domains contribute to the rendered output of the website. In this poster, we present the Web Dependency Analyzer, a tool that is designed to automatically infer the domains that a website depends on and further analyze the impact of each domain on the rendered output of the site. Our Web Dependency Analyzer instructs a headless web browser to infer the resource dependencies from a large set of input domains and outputs the visual impact of the unavailability of each domain.
