High precision location information formulates the basis of many modern wireless location based services (LBS). However, location privacy becomes an important issue along with the advantages that LBS offers. In this paper, we first show that, a novel eavesdropper is able to perform position estimation of the agent by purely overhearing the measurement signals between agents and anchors, using a time...
In this letter, we consider the scheduling and resource allocation problems in asynchronous ultra wideband cooperative localization networks, where the round trip measurements are applied for range estimation. A general non-data-aided cooperative scheduling strategy is first presented, where the reply signals can be identified by different frequency bands. Therefore, extra information, such as node...
A new mixed location algorithm for WSN is proposed in this paper. The distance is calculated based on DV-Hop algorithm, and the initial position is estimated by Centroid algorithm, then the result is optimized by Mass-spring optimization. MATLAB simulation result shows that, compared with DV-Hop, the error of the mixed algorithm is reduced about 15%. It does not need additional hardware, and the positioning...
