Abstract: The present paper proposes a network of mobile sensors in order to remotely measure concerning environmental parameters. Taking advantage of wireless technology, the system is able to exchange commands and data in numeric format with a querying remote client; displaced in a wide area to be monitored, each measurement module is equipped with an isotropic electromagnetic field smart sensor and a GPS module. Acquired data, according to a fixed sampling rate, are transmitted to a remote PC for processing stage, by GPRS networks. Several solutions have been undertaken for reducing noises and error contributes and the measurement system has been characterized in terms of uncertainty, in order to guarantee reliability and accuracy. Data processing optimization is performed by a fuzzy algorithm, previously tested, so getting the qualification of the decision-making stage with particular attention paid to the statistical features of monitored process.
Keywords: mobile smart sensors, wireless communication, remote environmental monitoring, decision-making, alarm reporting
