For the problem of coverage overlapping areas and blind spots in directional sensor networks, this paper introduced a virtual potential field based coverage algorithm for directional sensor networks (PCAFD) involving the concepts of overlapping centroid and effective centroid. Through the interaction between overlapping centroid and effective centroid, the algorithm led node sensor direction rotated by a virtual potential force. And it was directed towards the improvement of border conditions and node movements occurring during network optimization. This algorithm increased network coverage quickly. A series of emulation verifies the effectiveness of the algorithm. [ABSTRACT FROM AUTHOR]
