Formulate Full View Camera Sensor Coverage by Using Group Set Coverage.

Full view is an important subject in the study of wireless camera sensor coverage. It involves three issues, camera direction selection, camera location selection, and moving-directional target coverage. In this paper, we study them step by step, from one issue, two issue, to three issues. In each step, we formulate a group set cover- age problem, and study its computational complexity and approximation solutions. Especially, we employ a new type of approximations, the global approximation of local optimality for nonsubmodular optimization.
