Picture a highway with networked autonomous cars driving along it. On a serene, cloudless day, these cars need only exchange thimblefuls of data with one another. Now picture the same stretch in a sudden snow squall: The cars rapidly need to share vast amounts of essential new data about slippery roads, emergency braking, and changing conditions.
These two very different scenarios involve vehicle networks with very different computational loads. Eavesdropping on network traffic using a ham radio, you…
