Research on Survival Extension Strategy for Underwater Sensor Network Based on Ant Colony Algorithm
With the advancement and implementation of the ocean power strategies,underwater sensor networks have been widely used in the fields of marine resource detection,pollution monitoring,auxiliary navigation and underwater military reconnaissance,which are of great significance.Due to the difficulty in charging or replacing the batteries carried by the underwater sensors,how to reduce the transmission energy consumption and improve the lifetime of networks under the condition of limited sensor energy is one of the key issues that needs to be solved urgently.Accordingly,a dynamic ant colony routing algorithm is proposed,which considers the node residual energy after each transmission as one of the conditions for path optimization,the optimal path is selected in each transmission based on ant colony algorithm.Meanwhile the routing table is updated afterwards,so as to involve more nodes in the transmission and improve the node utilization.The simulation results show that,the dynamic ant colony routing algorithm takes into account both energy consumption balance and minimum energy consumption at the same time,which greatly improves the network lifetime.The analysis results have certain reference significance for the design of routing protocol of underwater sensor network.
