Online Observation ErrorModel Estimation for Acoustic Sensor Network Synchronization

Acoustic sensor network clock synchronization via time stamp exchange between the sensor nodes is not accurate enough for many acoustic signal processing tasks, such as speaker localization. To improve synchronization accuracy it has therefore been proposed to employ a Kalman Filter to obtain improved frequency deviation and phase offset estimates. The estimation requires a statistical model of...

Wireless sensor network design through genetic algorithm

In this paper, we study WSN design, as a multi-objective optimization problem using GA technique. We study the effects of GA parameters including population size, selection and crossover method and mutation probability on the design. Choosing suitable parameters is a trade-off between different network criteria and characteristics. Type of deployment, effect of network size, radio communication...

Sensor network design for the estimation of spatially distributed processes

In a typical moving contaminating source identification problem, after some type of biological or chemical contamination has occurred, there is a developing cloud of dangerous or toxic material. In order to detect and localize the contamination source, a sensor network can be used. Up to now, however, approaches aiming at guaranteeing a dense region coverage or satisfactory network connectivity...

Duality of Sensor Network Design Models for Parameter Estimation

Plant-performance evaluation relies on the estimation of specific variables, which could be model parameters or performance indicators. Thus, the availability of reliable process knowledge is essential to peformance evaluation. This information is obtained through monitoring and data reconciliation only when an adequate set of instruments has been located at the right places. The measurement ar...

Network design for distributed consensus estimation over heterogeneous sensor networks

This paper considers distributed estimation over heterogeneous sensor networks. We propose a distributed estimation strategy based on PageRank algorithm, where the link weight depends on the edge estimation covariances. We prove that the proposed estimator obtains better estimates than one typical estimator under identical initial conditions. Motivated by the advantage of the sensors with high ...
