In order to solve the problems of wireless sensor networks（ WSNs） coverage

such as uneven distribution

long deployment time and low coverage rate

propose a novel optimization strategy of WSNs coverage based on improved artificial bee colony（ ABC） algorithm. This method improves the observation bee selection operator by introducing covering rate factor（ CovRate）

and combines with the feedback strategy to improve the search process

the convergence rate and the efficiency. Simulation results show that the method uses fewer iterations to achieve more uniform distribution of the sensor

higher network coverage rate

and effectively reduces the redundant of sensor nodes

and network energy consumption

and prolongs the life cycle of WSNs.
