Abstract—In recent years, various researches have been conducted in order to find ways to cover a target or groups of targets with priority based target coverage and sensor deployment mechanisms taking the front seats. However, with these researches, effective target coverage has been a recurrent issue due to various factors like conflict between sensors and excessive waiting time for targets to be covered. In this paper, we proposed an algorithm based on queuing theory in tandem with mobile crowd sensing to tackle these issues. To do this, first, we develop some models which are based on the birth-and-death mechanism (one of the tools in queuing theory) to determine how long a target has to wait, the mean busy period of sensors and mean idle period of sensors. While developing these models, we considered cases where there exist a single sensor and n-sensors in the system. Based on these models, we developed the required algorithm. The simulation result shows that as the number of sensors increase relative to the number of targets, an average time before a target gets discovered is 0.2 seconds and sensor utilization decreasing towards zero as the number of sensors increases.
