A Fuzzy Logical Based WSN Node Self-Locating Means

A WSN (Wireless Sensor Network) node self-locating means which utilized the position information of anchor nodes is proposed in this paper. There are two types of nodes in the objective network of the means. The first type is the anchor node that equipped GPS (Global Position System) unit, their exact position can be gained. The second type is normal node that supports RSS (Received Signal Strength) based ranging. With the help of anchor node, the normal nodes fulfill a low complexity, coarse-grained, RSS ranging based fuzzy logical locating algorithm, to determine their own positions. Theoretical analysis showed that, the proposed means can provide fine location accuracy with a relative low cost and complexity.
