Acyclic flow networks, present in many infrastructures of national importance (e.g., oil & gas and water distribution systems), have been attracting immense research interest. Existing solutions for detecting and locating attacks against these infrastructures, have been proven costly and imprecise, especially when dealing with large scale distribution systems. In this paper, to the best of their knowledge for the first time, the authors investigate how mobile sensor networks can be used for optimal event detection and localization in acyclic flow networks. They propose the idea of using sensors that move along the edges of the network and detect events (i.e., attacks).
