In order to improve area coverage rate of wireless multimedia sensor networks( WMSNs)
after sensor nodes are randomly deployed
by regulating sensing direction of sensor nodes
enable node rotates from perception overlapping areas to cover blind areas
so as to enhance network coverage rate. Aiming at problem of existing algorithms that coverage efficiency and covering rate can’t be unified
propose an improved virtual force algorithm related with coverage redundancy( VFARCR)
the algorithm using sensor nodes to sense repulsion between the centroid point of fan-shaped area
adjust sensing direction
and size of direction adjusting is determined by coverage redundancy
virtual force and coverage redundancy control rotating of sensor collectively. Simulation results show that the algorithm improves coverage efficiency and coverage effect and improve performance of virtual force covering algorithm.
