A Distributed Anchor Node Selection Algorithm Based on Error Analysis for Trilateration Localization

This paper proposes a distributed anchor node selection algorithm based on error analysis for trilateration localization (EATL). The influence of distance measurement error on localization accuracy is discussed from two aspects: condition number of triangle formed by the three anchor nodes and the r...
