%X To improve the quality of coverage for monitoring a moving target (event) in mobile sensor networks (MSNs), this paper first formulates a monitoring evaluation criterion based on Voronoi partition, then proposes a distributed flocking based control algorithm. This paper adopts an algorithm which combines the least square method with the consensus algorithm to estimate the relative position of the target. Compared to traditional methods, only local and 1-hop neighborhood (measurable) information is required, hence it reduces the communication time and energy consumption. While optimizing the quality of monitoring (QoM), it also regulates all sensors' velocities to the target velocity, hence the topology of the network is kept better and the total energy consumption on movement of sensors is reduced. With the assumption that the target is moving at a constant velocity or its acceleration is available all sensors, the velocities of all sensors would be asymptotically aligned with the target velocity and QoM would converge to a local maximum. The estimation algorithm for the relative position to the target is simple and effective.
