英文摘要：

Aiming at problem of coverage overlapping areas and blind spots that nodes deployed randomly in directional heterogeneous sensor networks,introduce a virtual potential field-based coverage algorithm for directional heterogeneous（ PCADH） networks inspired by virtual potential field algorithm. Through involving concepts of overlapping centroid,effective centroid and virtual boundary centroid to the model,this algorithm carries out optimization processing of virtual force,node advance and return movements and boundary in directional heterogeneous networks based on directed perception model. Simulation results show that the proposed algorithm can improve coverage rate of directional heterogeneous sensor networks rapidly and effectively.
