“…While in underground WSNs [29] and in-solid scenarios [30] where seismic/vibrational sensor data are processed, the propagation speed is unknown and depends strongly on the propagation medium [31], [32]. In fact, localization of single or noncollaborative sources with anchor location errors have been addressed in [33]- [37] which show that positioning accuracy will be improved when the receiver location uncertainty is taken into account. Recently, a pioneering work for the scenario of WSNs has been presented in [13].…”

Abstract-Finding the positions of nodes in an ad hoc wireless sensor network (WSN) with the use of the incomplete and noisy distance measurements between nodes as well as anchor position information is currently an important and challenging research topic. However, most WSN localization studies have considered that the anchor positions and the signal propagation speed are perfectly known which is not a valid assumption in the underwater and underground scenarios. In this paper, semi-definite programming (SDP) algorithms are devised for node localization in the presence of these uncertainties. The corresponding Cramér-Rao lower bound (CRLB) is also produced. Computer simulations are included to contrast the performance of the proposed algorithms with the conventional SDP method and CRLB.Index Terms-Node localization, range measurements, semi-definite programming, sensor networks.

Figure 9 shows the MSEs when there is receiver position uncertainty and the results of [16] are also included. The performance of the proposed scheme is in between [15] and [16], and all cannot attain CRLB.…”

In this paper, a new semi-definite programming approach is devised for approximating nonlinear estimation problems. The main idea is to include the noise components as parameters of interests, which increases the flexibility in the convex optimization formulation. Using the source localization as an illustration, we develop semi-definite relaxation (SDR) positioning algorithms using angle-of-arrival, time-of-arrival and time-difference-of-arrival measurements. Numerical examples are included to show the effectiveness of the proposed SDR approach.

Abstract-This paper considers the application for tracking of one mobile emitter using a sequence of frequency difference of arrival (FDOA) measurements obtained by single pair of receivers at a time. We suppose there is only one unmanned aerial vehicle (UAV) as emitter without data link relation problems, such as disconnection of data link or false measurements. Each FDOA measurement defines a region of possible emitter locations around a unique hyperbola. These analysis leads to the Cramér-Rao lower bound (CRLB) for estimation of movements. Through the analysis we propose the manner for tracking through the error-ellipsoids acquired from each CRLB. Since the performance measure is the length of error ellipsoid axes, we compare the effects of various environments.Index Terms-Frequency difference of arrival (FDOA), Cramér-Rao lower bound (CRLB), unmanned aerial vehicle (UAV), tracking, ground station (GS)
