【Abstract】 After researching the anti-monitoring problem on mobile objects in the heterogeneous sensory field,a new Exposure model is proposed,which can be used to estimate the approximate risk of a mobile object moving along a path to traverse the sensory field deployed with anisotropic sensor nodes.Based on the newly proposed Exposure model,a novel decision algorithm for path selection is designed by combing the Anisotropic Voronoi Tessellation schemes,which guarantee that the mobile object can select a suitable path with a minimal approximately risk of traveling across the anisotropic sensory field.Theoretical analyses and simulation results show that the new algorithm has a good anti-monitoring performance and requires only that the mobile object should know the local information in its detection radius,so it is distributed and practical.更多还原
