This paper presents a distributed fermat-point range estimation strategy, which is important in the moving sensor localization applications. The fermat-point is defined as a point which minimizes the sum of distances from three sensors inside a triangle. This point is indeed at the trianglepsilas center of gravity. We solve the problems of large errors and poor performance in the bounding box algorithm...
The accuracy of location information is critical for many applications of wireless sensor networks (WSN), especially those used in hostile environments where malicious adversaries can be present. Since it is impractical to have a GPS device on each sensor in WSN, most of the existing location discovery schemes can only be used in the trusted environment. Recently, some advanced research has addressed...
