In this study, received signal strength indicator (RSSI) based indoor localization is investigated in sparse-anchor-deployment environments. Multipath propagation, dynamical variations in propagation model parameters and antenna patterns which are three of many potential error sources of indoor RSSI-based localization are experimentally analyzed. Possible enhancements so as to minimize the effects of mentioned problems are examined. A multichannel maximum-likelihood estimation (MLE) algorithm is proposed and implemented in a testbed together with some existing localization algorithms. A performance comparison of the implemented methods is provided. It is shown that the suggested method can increase the accuracy of indoor RSSI-based localization in low anchor density by using multichannel measurements and real-time propagation parameter estimation.

An Analysis for the Correlation of Coverage and Spatial Resolution for Wireless Sensor Networks
Tomur, Emrah; Erten, Y. Murat (2007-12-10)
In this study, we investigate the interactions between coverage and spatial resolution for cluster-based wireless sensor networks (WSN). We present an approximate probabilistic analysis for the mentioned correlation and verify this analysis by simulation. Our analysis includes the k-coverage case.
On localization and tracking using received signal strength measurements /
Yılmaz, Alptekin; Yılmaz, Ali Özgür; Orguner, Umut; Department of Electrical and Electronics Engineering (2015)
In this study, first, some received signal strength (RSS) based localization techniques, including maximum likelihood estimation (MLE), multidimensional scaling (MDS) and weighted least squares (WLS), are investigated and compared to each other via a simulation study within the perspective of a collaborative localization scenario. MLE using RSS measurement model, called RSS-MLE is known in the literature to be significantly biased. An important observation of this work is that the aforementioned bias can be...
On event signal reconstruction in wireless sensor networks
Atakan, Baris; Akan, Oezguer B. (2007-05-18)
In Wireless Sensor Networks (WSN), the effective detection and reconstruction of the event signal is mainly based on the regulation of sampling and communication parameters used by the sensor nodes. The aim of this paper is to understand the effect of these parameters on the reconstruction performance of event signal in WSN. Theoretical analysis and results show that with proper selection of sampling and communication parameters, the event signal can be satisfactorily reconstructed at the sink. Furthermore,...
Symbol synchronization for MSK signals based on matched filtering
Sezginer, Serdar; Tanık, Yalçın; Department of Electrical and Electronics Engineering (2003)
In this thesis, symbol timing recovery in MSK signals is investigated making use of matched filtering. A decision-directed symbol synchronizer cascaded with an MLSE receiver is proposed for fine timing. Correlation (matched filter) method is used to recover the timing epoch from the tentative decisions obtained from the Viterbi algorithm. The fractional delays are acquired using interpolation and an iterative maximum search process. In order to investigate the tracking performance of the proposed symbol syn...
A Comparison of sparse signal recovery and approximate bayesian inference methods for sparse channel estimation
Uçar, Ayla; Candan, Çağatay; Department of Electrical and Electronics Engineering (2015)
The concept of sparse representation is one of the central methodologies of modern signal processing and it has had significant impact on numerous application fields such as communications and imaging. Sparsity expresses the idea that the information rate of a continuous time signal may be much smaller than suggested by its bandwidth, or that a discrete time signal depends on a number of degrees of freedom which is comparably much smaller than its (finite) length. With recent advances in sparse signal estim...
