Aimed at disadvantages on most existing coverage control algorithms for directional sensor networks

such as finite orientations

the restrained degree of optimization

the deficient applicability of these algorithms etc.

a coverage control strategy（CCS） was presented

which was strictly deduced from some mathematic properties.A distributed algo-rithm generated from the CCS could be extensively used in different kinds of networks with different sensing models.Simulation results and performance analysis illustrate that the CCS can efficiently enhance the coverage of networks and show the certain superiority comparing to existing algorithms of the same kind.
