Sensor network presents us many new challenging practical and theoretical problems. This paper is concerned with minimal exposure problem in sensor networks. Exposure, proposed by Megerian and others  as a useful metric to describe the sensor coverage of a path in a sensor ﬁeld, exhibits interesting properties and induces related open problems. In this paper, we present a solution to an open one-sensor exposure problem [2, 3] using variational calculus as our ﬁrst step in further understanding of the exposure problem in multiple sensor scenarios.
