“…The scientific community has made extensive use of satellite image data for mapping land cover and estimating geophysical characteristics such as land surface temperature (LST). However, recent work exploits the emerging field of WSN as an alternative and operative method for LST validation measurements [15], in which the proposed calibration algorithm was implemented in order to correct the systematic errors (biases) that impact the authenticity of the data collected by different sensors.…”

Wireless sensor networks offer flexibility to monitor environmental conditions. However, in some hostile environments with changing propagation occurrences, it is challenging to guarantee a network free from systematic errors (biases), those errors can corrupt the data gathered from the network. The authors intend to address this problem using a Bayesian approach. This study presents a new Bayesian wireless network model based on a belief propagation algorithm over a noisy communication, to seek the calibration of the network for correlated sources. They set up a point-to-point communication model, consisting of a frequency modulation signal at the transmitter and a discrete-time phase-locked loop structure at the receiver over an additive white Gaussian noise channel. Then, they use a Bayesian approach to model the propagation of information, and analyse the noise impact on their system. The simulation results show significant improvement within a few time instants in the mean squared error of the sensors internal states. An evaluation in a noisy environment confirms the robustness of the proposed system.

The growth of wireless technology due to global population growth and urbanization has increased internet usage, intensifying network energy demands. Researchers and professionals prioritize energy efficiency to cut costs and reduce emissions, with a focus on wireless networks. This chapter explores energy efficiency's importance, particularly in ad hoc wireless and sensor networks. This study seeks to maintain energy efficiency while maximizing resources like node numbers, using computational methods and data envelopment analysis (DEA) with multicast incremental power (MIP) and coded packet algorithms as DEA inputs. An output-oriented DEA approach enhances network performance by increasing output while maintaining input resources. This research contributes significantly to understanding energy efficiency in wireless networks, providing valuable insights for network administrators and decision-makers, particularly in ad hoc wireless networks.
