In today’s manufacturing environment, delay in monitoring output performance might cause production mess in the industry. Therefore, an efficient communication and real time feedback to maximize uptime and improve productivity seems vital. Adapting the capabilities of RFID technology and Wireless Mesh Sensor Network (WMSN) through web-based monitoring system might solve this problem. Thus, an embedded system namely ERFIDC was developed as a potential solution in addressing this demand. This paper reports the proposed embedded system architecture and evaluation of its reading range in point-to-point and WMSN setup at the selected production plant.

Abstract. People are becoming increasingly interested in mobile air quality sensor network applications. By eliminating the inaccuracies caused by spatial and temporal heterogeneity of pollutant distributions, this method shows great potentials in atmosphere researches. However, such system usually suffers from the problem of sensor noises and drift. For the sensing systems to operate stably and reliably in the real-world applications, those problems must be addressed. In this work, we exploit the correlation of different types of sensors caused by cross sensitivity to help identify and correct the outlier readings. By employing a Bayesian network based system, we are able to recover the erroneous readings and re-calibrate the drifted sensors simultaneously. Specifically, we have (1) designed a Bayesian belief network based system to detect and recover the abnormal readings; (2) developed methods to update the sensor calibration functions in-field without requirement of ground truth; and (3) deployed a real-world mobile sensor network using the custom-built M-Pods to verify our assumptions and technique. Compared with the existing Bayesian belief network technique, the experiment results on the real-world data demonstrate that our system can reduce error by 34.1 % and recover 4 times more data on average.
