- Abstract
Internet of things (IoT) is a ubiquitous network that helps the system to monitor and organize the world through processing, collecting, and analyzing the data produced by IoT objects. The accurate localization of IoT objects is indispensable for most IoT applications, especially healthcare monitoring. Utilizing GPS as the positioning system is not cost‐efficient and does not apply to some environments (e.g., deep forests, oceans, inside the buildings, etc.). Hereupon, copious position estimation approaches are developed in the literature. Among range‐free approaches, distance vector‐Hop (DV‐Hop) is the widely used algorithm due to its straightforward applicability and can estimate the position of unknown objects that are far‐off the anchors. Due to its low accuracy, various techniques were proposed to increase the accuracy of basic DV‐Hop. In the most recent approach, meta‐heuristic algorithms were used, the results of which were promising. In the present paper, Tunicate Swarm Algorithm and Harris hawk optimization were initially hybridized. Afterthought, the resulting hybrid algorithm was enhanced by appending a new phase. Then, the proposed hybrid algorithm was intermingled with the DV‐Hop algorithm. In the first set of experiments, the proposed hybrid algorithm was evaluated on 50 test functions using average, SD, box plot, and p‐value criteria. In the second part, the proposed localization algorithm's efficiency was investigated in twenty‐eight different manners using node localization error, average localization error, and localization error variance metrics. The effectiveness of the contributions was evident from the experimental results.
