Abstract: Positioning is the basic function of wireless sensor networks (WSN). At present, range-based positioning is a common method to obtain the position of a node, but its accuracy has encountered a bottleneck. The fundamental reason is that it ignores the ranging information between blind nodes. Therefore, based on the design of the positioning optimization factor to adjust the weight of the ranging information between the blind nodes, the positioning model of minimizing the error is established. On the basis of de… Show more

“…To the present author's knowledge, most of the literatures on applications of WOA in WSN localization use range-based techniques [28][29][30][31][32]. The experimental results show that the proposed schemes achieve better localization accuracy, delivery radio, and delay.…”

“…In response to these shortcomings, researchers have improved WOA, such as chaotic WOA [18,19], improved WOA [20,21], binary WOA [22,23], hybrid WOA [24,25], and multi-objective WOA [26,27]. In recent years, WOA has been employed in range-based node localization algorithms [28][29][30][31][32], but few applications in DV-Hop. For instance, Chai et al [33] only utilized parallel techniques to improve WOA and applied it to enhance the performance of DV-Hop, but they do not take into account the memory consumption and storage capacity of the node.…”
