Power-Efficient Direct-Voting Assurance for Data Fusion in Wireless Sensor Networks

Abstract: Wireless sensor networks place sensors into an area to collect data and send them back to a base station. Data fusion, which fuses the collected data before they are sent to the base station, is usually implemented over the network. Since the sensor is typically placed in locations accessible to malicious attackers, information assurance of the data fusion process is very important. A witness-based approach has been proposed to validate the fusion data. In this approach, the base station receives the fusion da… Show more

“…The detection of certain events is made viable through data sensing and forwarding from sensor nodes to the so-called sink node for further processing [18]. As such, the occurrence of any unexpected circumstance normally involves communication of outstanding data to the sink node.…”

“…Detection, classification and identification algorithms used in low level processing are based on future-based inference techniques, physical models and cognitive-base models [8]. Examples of these methods easily can be found in the literature based on parametric techniques such as classical inference of probability [9]- [12] or Bayesians inference [13]- [16]. Method based on physical models with estimation of Kalman Filtering can be found in [17]- [22] or least squares technique [23]- [26] and methods based on cognitive-based models can be reviewed in [21]- [23].…”

“…For information assurance of the data fusion in WSN, a witness based approach has been demonstrated to verify the fusion data [8]. An improved witness-based approach using a direct voting mechanism has also been proposed to verify the fusion data without any cryptographic operation [10].…”
