Using sonar to detect submarines used to be an effective method. Current technologies, however, have made it possible for submarines to thwart standard (active or passive) sonar mechanisms. One viable alternative is to use magnetic or acoustic sensors in close proximity to possible underwater pathways a submarine may pass through. This approach may require deploying large-scale underwater sensor networks to form strong barriers for coastline protection. Previous work has focused on 2-dimensional sensor networks. The authors show new results for 3-dimensional sensor networks which are fundamentally different. They first prove that there is no strong barrier coverage in a large 3-dimensional fixed emplacement sensor field where sensor locations follow a Poisson point process.
