Summary:
As a novel technique which can effectively improve precious electromagnetic spectrum sources, cognitive radio is widely discussed in various aspects. Many applications in cognitive radio request position information of the primary users should be achieved during radio-sensing analysis process, so localization algorithm becomes an important issue in related researches. In this paper, we propose a practical robust distributed localization (RDL) algorithm for cognitive radio. This algorithm can make secondary nodes effectively and accurately get the location information of primacy users, even if measurement error of distance exists. Simulation results which can confirm our conclusion are also shown in this paper.
