A Survey on Multi-Dimensional Path Planning Method for Mobile Anchor Node Localization in Wireless Sensor Networks.

Node localization is one of the key technologies in wireless sensor networks, which provides technical support for many location-based applications. In the process of node localization, due to the limitation of cost and energy consumption of wireless sensor networks, mobile anchor nodes more suitable for localization as a way to reduce costs. However, to the best of our knowledge, there has been no comprehensive and in-depth study dedicated to the problem of assisted localization of mobile anchor nodes for multidimensional wireless sensor networks in the last decade, as well as there are no latest research reports reflecting the latest progress in this field. In this paper, we focus on a detailed study of the mobile anchor node assisted localization problem for multidimensional wireless sensor networks. Firstly, a model for mobile anchor node assisted localization is described. Then static path planning and dynamic path planning methods for mobile anchor nodes in 2D and 3D environments are introduced, respectively, and compare them in terms of localization environments, number of mobile anchor nodes, mobile model, area full coverage, energy consumption of anchor nodes, localization ratio, localization error and path length. Finally, problems of the existing methods in this field and the possible future research directions are discussed. Intended to provide reference for researchers in this field and enable readers to gain a deeper understanding of Multi-Dimensional Path Planning Method for mobile anchor node Localization in wireless sensor networks (MDPPML), as well as research trends and future research directions in this field.
