IBM and The Weather Company use edge computing to issue vital alerts Video Description

Usually, a government-issued message is broadcast via a cell tower to all devices within its range. When that network goes down, however, so does the ability to send alerts. Using the Weather Channel app, peer-to-peer technology converts mobile devices into links within the mesh network, allowing devices to talk directly to each other without using cell tower infrastructure. Each smartphone becomes a node that stores the message and passes it to the next nearest device, creating a daisy chain to reach more devices and remove the need for a cellular network. While other mesh networks use hotspotting, IBM and The Weather Company chose not to turn devices into individual access points to avoid excessive battery drain.
