摘　　要：针对水下声学传感器网络中锚节点稀少的问题,给出了一种分布式的水下节点自定位算法。为配合定位算法的完成,提供定位过程所需的邻接信息表等信息,提出了一种分布式的并发数据传播算法,并针对该数据传播算法中存在的通信冲突问题,给出了冲突解决策略。仿真试验验证了上述两种方法配合完成水下节点定位的可行性和有效性。With the problem of sparse anchor nodes in underwater acoustic sensor networks,a distributed node localization algorithm is put forward.In order to provide the information for node localization algorithm such as the neighborhood relation tables,a distributed and concurrent data transmission algorithm is presented which includes a conflict solving strategy dealing with the communication conflict during the data transmission process.Simulation experiments demonstrate the feasibility and validity of localization algorithm by using these combined methods.
