Abstract
In wireless sensor networks (WSNs), localization is very important because there are many applications which depend on the location of a sensor node. Among various WSNs localization techniques, ranging methods based on received signal strength (RSS) are most popular because of simplicity and no additional hardware requirement. However, RSS ranging suffers from various environmental conditions and it can give an erroneous range for positioning of a node. Hence, it is necessary to deal with ranging error efficiently. In order to efficiently find the position of a node in the presence of RSS ranging error, we introduce a novel localization technique in this paper. To apply our positioning concept, our method selects three most suitable reference nodes according to RSS and geometry of reference nodes. We compare our simulation results with, localization with dynamic circle expanding mechanism (LoDCE), which clearly show that our method outperforms it.
