Best and Worst-case Fuzzy Geometric Coverage in Sensor Networks
The sensing abilities of networked sensors are afiected by environmental factors and their own degeneration such that the sensing abilities reduce to a smaller value,then a fuzzy annulus is formed.So it is fuzzy to anticipate this sensing behavior.We investigate the coverage issues in sensor networks based on fuzzy theory and propose a new notion of fuzzy geometric coverage.Based on this model,we define the best and worst-case fuzzy geometric coverage,and construct the Delaunay diagram and Voronoi diagram to solve the problem.The analysis and simulation results show that the proposed model has a good performance In solving tuzzy coverage problem m sensor networks.
