Design and Implementation of an Underwater Acoustic Integrated Networking-positioning System
摘要
Abstract
Underwater acoustic networks have been widely studied and applied in the fields of three-dimensional acquisition,transmission,and perception of ocean information.The location of nodes in underwater acoustic networks is an important information needed in the protocol design and diverse application of underwater acoustic network.Conventional positioning solutions which rely on Global Positioning System and use conventional underwater acoustic positioning technology to obtain the location of underwater acoustic network nodes encounter problems such as inability to directly apply underwater,low efficiency in multiple node localization,and the requirement for precise time synchronization.In this paper,a scheme for underwater acoustic integrated networking-positioning(UAINP)is presented.In this scheme,by using the interaction between network nodes during the operation of underwater acoustic networks,a response-ranging capability can be provided to solve the node position,thus integrated communication and positioning capability that does not requirement for precise time synchronization can be achieved without affecting the network communication.The design details of core modules such as network communication,ranging,positioning,error compensation,etc.,are provided.Then,a small-scale experimental underwater acoustic integrated networking-positioning system is developed and evaluated via lake trial.The results of the lake trial preliminarily demonstrate the effectiveness of the integrated networking-positioning capabilities of the proposed system.关键词
