Wireless sensor networks have been used for a variety of purposes such as habitat monitoring, malicious target detection, and climate observation. Conventionally, stationary sensors are used to carry out sensing tasks in a region of interest. However, if the region is much larger than the sensing range of a single sensor, stationary sensor networks could incur many problems such as the complicated reciprocal effects between coverage and communication ranges. This paper proposes a method to collect sensing data by mobile sensors. The method first selects critical sensing locations using detection performance as a metric.
