Mobile anchor path planning techniques have provided as an alternative option for node localization in wireless sensor networks (WSNs). In such context, path planning is a movement pattern where a mobile anchor node's movement is designed in order to achieve a maximum localization ratio possible with a minimum error rate. Typically, the mobility path planning is designed in advance, which is applicable when the mobile anchor has sufficient sources of energy and time. However, when the mobility movement is restricted or limited, a dynamic path planning design is needed. This paper proposes a novel distributed range-free movement mechanism for mobility-assisted localization in WSNs when the mobile anchor's movement is limited. The designed movement is formed in real-time pattern using a fuzzy-logic approach based on the information received from the network and the nodes' deployment. Our proposed model, Fuzzy-Logic based Path Planning for mobile anchor-assisted Localization in WSNs (FLPPL), offers superior results in several metrics including both localization accuracy and localization ratio in comparison to other similar works.
移动锚点路径规划技术为无线传感器网络(WSN)中的节点定位提供了一种替代方案。在这种情况下,路径规划是一种移动模式,其中移动锚点节点的移动被设计为以最小的错误率实现尽可能高的定位率。通常,移动性路径规划是预先设计的,当移动锚点有足够的能量和时间来源时适用。然而,当移动性受到限制时,就需要动态路径规划设计。本文提出了一种新颖的分布式无距离移动机制,用于在移动锚点移动受限的情况下,在无线传感器网络中进行移动辅助定位。所设计的移动是基于从网络接收的信息和节点部署,使用模糊逻辑方法以实时模式形成的。我们提出的模型,即无线传感器网络中基于模糊逻辑的移动锚点辅助定位路径规划(FLPPL),与其他类似工作相比,在包括定位精度和定位率在内的多个指标上都提供了更好的结果。
