%X We studied several fundamental key issues of localization in underwater sensor networks(UWSNs),then proposed an multi-frequency active localization method(MFALM) based on the time difference on arrival(TDOA) for UWSNs.The method,which is event-driven,divides all the nodes into three groups:buoy nodes,relay nodes,and ordinary nodes.To guarantee the low-power and effectiveness of communication,the nodes communicate with each other by two types of frequencies:low frequency and high frequency,the former is used...
