Bottom Line: We first propose two simple multi-point surveillance schemes for a moving target in a WSN and demonstrate that one of the schemes can achieve high tracking probability with low power consumption.In addition, we examine the relationship between tracking probability and sensor density through simulations, and then derive an approximate expression representing the relationship.As the results, we present guidelines for sensor density, tracking probability, and the number of monitoring sensors that satisfy a variety of application demands.

ABSTRACT
In this paper, we focus on the problem of tracking a moving target in a wireless sensor network (WSN), in which the capability of each sensor is relatively limited, to construct large-scale WSNs at a reasonable cost. We first propose two simple multi-point surveillance schemes for a moving target in a WSN and demonstrate that one of the schemes can achieve high tracking probability with low power consumption. In addition, we examine the relationship between tracking probability and sensor density through simulations, and then derive an approximate expression representing the relationship. As the results, we present guidelines for sensor density, tracking probability, and the number of monitoring sensors that satisfy a variety of application demands.

Mentions: Figure 15 compares the simulation results with the approximate formula. As shown in Figure 15, these values show a similar trend. As a result, we can derive a reliable approximate formula for the relationship between the number of monitoring sensors and the tracking probability.
