Researchers from City College of New York, Harvard University, and Johns Hopkins University have developed Amigo, a prototype mesh network specifically designed to maintain communication during political protests and internet blackouts imposed by authoritarian regimes. The system addresses critical failures in existing mesh network technology that have plagued protesters in countries like Myanmar, India, and Bangladesh, where governments routinely shut down internet connectivity to suppress civil unrest.
Traditional mesh networks create local area networks by connecting smartphones directly to each other, allowing users to bypass conventional wireless infrastructure. However, these systems have historically struggled with messages failing to deliver, appearing out of order, and leaking compromising metadata that allows authorities to trace users. The primary technical challenge occurs when networks experience strain, causing nodes to send redundant messages that flood and collapse the system.

Amigo overcomes these limitations through an innovative approach that dy
