A multi-objective modeling of K-coverage problem under accuracy constraint

In recent years, wireless sensor networks have become attractive for tracking and target surveillance. For these applications, the accuracy is an important constraint. In this paper, we study a multi-objective sensor placement problem taking into account the K-coverage and the accuracy. The objectives are the maximization of the K-coverage and the minimization of the number of deployed sensors, under an accuracy constraint. A linear formulation and an adaptation of the NSGA-II and Beam Search are proposed. Results show the NSGA-II is better than the BS heuristic for small instances but this trend is inverted for larger instances.
