In order to improve the automatic configuration and node optimal deployment ability of offshore wireless sensors,an optimal configuration method of offshore wireless sensors based on genetic algorithm is proposed.The node equilibrium deployment model of offshore wireless sensor is constructed,the balanced control and adaptive adjustment of offshore wireless sensor node is carried out by using sensor output terminal link balancing configuration method,the automatic polling control protocol algorithm of offshore wireless sensor node is established,and the load balancing adjustment of offshore wireless sensor node is carried out with the method of adaptive weighted control.Combined with power consumption suppression method,the energy cost of offshore wireless sensor is reduced,and the optimal node configuration and channel equilibrium design of offshore wireless sensor are realized under the optimization of genetic algorithm.The simulation results show that the proposed method has good adaptability and strong balanced coverage ability for offshore wireless sensor configuration and node deployment,which improves the stability and life cycle of the sensor network.
