Abstract

In underwater wireless sensor networks, distance-related localisation technologies rely on acquiring distance information between nodes to complete node location. Currently, ranging algorithms generally have the problems of high energy consumption and low accuracy. Therefore, a new ranging algorithm is proposed. In this algorithm, an information transmission mechanism is designed to transmit ranging information efficiently. Based on this mechanism, when the network clock is asynchronous, the information propagation time between nodes is obtained by a small number of asymmetric information sending and receiving operations. Furthermore, a selection method for the master beacon node is designed to balance the energy consumption of the nodes. To solve the problem of signal propagation path non-linearity caused by stratification effect, a signal emergence angle fast iterative method based on the known sound speed profile information is developed to calculate the distance between nodes. Simulation experiments demonstrate that the proposed algorithm is better than other state of the art algorithms in terms of energy consumption and network lifetime. In addition, the proposed algorithm can quickly solve the signal emergence angle, effectively reduce the impact of seawater sound speed layering and has good ranging accuracy in shallow seas.
