Lifetime and Coverage Guarantees Through Distributed Coordinate-Free Sensor Activation

In wireless sensor networks (WSNs), a large number of sensors perform distributed sensing of a target field. A sensor cover is a subset of the set of all sensors that covers the target field. The lifetime of the network is the time from the point the network starts operation until the set of all sensors with nonzero remaining energy does not constitute a sensor cover any more. An important goal in sensor networks is to design a schedule-that is,...
