Abstract: Recently,much attention has been paid to marine resources.Applications of underwater wireless sensor networks (UWSNs) in marine monitoring,underwater military defense,navigation and other aspects have caused wide concern.A good underwater wireless sensor network coverage control of UWSNs can reduce coverage redundancy and optimize the usage of the network resources.It can also reduce node energy consumption and prolong the life cycle of the node,so that the underwater wireless sensor network can better accomplish the goal of environment perception.This paper proposed a method of coverage control based on sequential game to optimize coverage control of underwater wireless sensor networks,which is expected to be able to reduce the energy consumption of the sensor nodes,balance the nodes energy,and achieve the goal of prolonging the network lifetime.Finally,we verified the effectiveness of the algorithm by simulation experiments in optimization of the network coverage and extension of the network life cycle.
