"Whether in the IoT or on social networks, there are many circumstances where old information is circulating and could cause problems - whether it's old security data or a misleading rumor," says Wenye Wang, co-author of a paper on the work and a professor of electrical and computer engineering at NC State.

"Ultimately, our work can be used to determine the best places to inject new data into a network so that the old data can be eliminated faster," says Jie Wang, a postdoctoral researcher at NC State and first author of the paper.

A highly interconnected network can disseminate new data very quickly.

The researchers also identified an algorithm that can be used to assess which point in a network would allow you to spread new data throughout the network most quickly.

"Practically speaking, this could be used to ensure that an IoT network purges old data as quickly as possible and is operating with new, accurate data," Wenye Wang says.
