A crucial concern for any network is security, and how to design sensor networks to detect and defend against intrusion — in other words, where to put sensors to ensure they detect intrusion. Researchers in this area have created applications specific to the design of sensor networks to detect security threats and provide support for security decisions in situations of uncertainty and time pressure, and have created decision-analysis detection mechanisms using stochastic modeling. This work has also extended to the natural world, with researchers using environmental sensors and ocean models to predict current flow in estuaries, to determine the best place to place sensors.

Professor Jeffrey Nickerson, along with fellow researcher Toshihiko Matsuka, of Japan, has received a patent related to work aiming to detect hostile intent from movement patterns.
