[Abstract] Mobile wireless sensor network (MWSN) is a novel technology for acquiring and processing information. It can perform complicated, large-scale monitoring and tracking tasks. In MWSN, localization of the mobile node is crucial for most applications. In this paper, we discuss the current status of node self-localization algorithms. We also introduce the basic methods of node localization and performance estimation index of localization algorithms. We analyze these popular localization algorithms, and disadvantages and solutions are discussed. We suggest that three-dimensional space will be a research trend.
