Coverage control is one of the basic problems in wireless sensor networks（ WSNs）

and dynamic coverage problem is valuable in many fields. Based on centralized Voronoi tessellation

and combined with the Lloyd algorithm

a dynamic coverage algorithm for WSNs is proposed

in order to achieve better results of the dynamic coverage. This algorithm achieves a dynamic WSNs coverage of the target domain through adjusting geometric boundaries of target coverage area and collaborative scheduling of WSNs nodes. In simulation

perform a square

a square with a circular obstacle inside static boundary covering experiments and square to rectangular target domain

square to crossing shape target domain

square to H-shaped target domain dynamic boundary covering experiments

effectiveness of control algorithm is demonstrated

and extent of coverage

coverage efficiency with different shapes of the target coverage area and different number of nodes are analyzed.
