Sensory Data Gather Technology with Mobile AUV for Sparse Underwater Sensor Networks
摘要
Abstract
Due to limited communication distance and high price of underwater acoustic nodes,underwater sensor networks are generally deployed in a sparse manner. Therefore,it is hard to guarantee overall network connectivity and data collection efficiency. AUV,which is a natural platform for mobile data collection,can overcome the short⁃comings of data acquisition with fixed Sink node. This paper proposed a mobile data collection mechanism with mo⁃bile AUV for underwater sensor networks. In the proposed mechanism,sensor nodes covered by AUV are regarded as temporary Sink nodes. The other sensor nodes transmit sensory data to temporary Sink nodes using minimum spanning tree(MST)transmission method. Finally,temporary Sink nodes gather data and deliver them to AUV. Along with the movement trajectory of AUV,sensory data of the whole networks can be collected in a simple and ef⁃ficient way. The simulation results verified that the proposed algorithm can improve data collection efficiency in the constraint of network energy consumption.关键词
