Abstract
Control of a set of sensors disseminated in the environment to monitor activity is a subject of the presented research. Due to redundancy in the areas covered by sensor monitoring ranges a satisfying level of coverage can be obtained even if not all the sensors are on. Sleeping sensors save their energy, thus, one can propose schedules defining activity for each of sensors over time which offer a satisfying level of coverage for a period of time longer than a lifetime of a single sensor. A new heuristic algorithm is proposed which searches for such schedules maximizing the lifetime of the sensor network under a coverage constraint. The algorithm is experimentally tested on a set of test cases and effectiveness of its components is presented and statistically verified.
