Abstract:

An artificial Bee Colony algorithm with multiple nectar sources based on interactive mechanism for coverage optimization of WSNs is proposed based on artificial bee colony and wireless sensor networks (WSNs),.The algorithm applies the selection strategy providing sensitivity as well as pheromone instead of roulette wheel rule during the exploiting process of onlookers.And interactive strategy is involved to accomplish the neighborhood search of onlookers.In addition,new nectar is generated by the OBL strategy to update the worst nectar at the end of each iteration.The simulation results show that the algorithm enables a more uniform distribution of the sensor nodes within the detection area,and achieves better network's overall coverage through a smaller number of iterations.It has a critical influence on prolonging the lifetime of the entire WSNs and reducing network energy consumption.
