Abstract:
The demand for Wireless Sensor Networks (WSN) applied to industrial process monitoring and control is increasing as the forth industrial revolution (Industry 4.0) gathers pace. Flexibility and low cost make WSN the perfect choice for these modern 21st century manufacturing plants. Small and Medium Sized Enterprises (SMEs) have an important role in the growth of developing economies as they account for approximately 60% of all private sector employment, but are currently finding it difficult to take advantage of new sensor technologies. This paper describes the tests carried out with a WSN in order to ascertain the relationship between the Received Signal Strength Indicator (RSSI) and the Packet Error Rate (PER). Subsequently, a new RSSI based network management strategy is presented; it includes two RSSI tracking indices that guarantee an early warning in case the radio signal deteriorates. Both indices are generated in real time; the first estimates the RSSI tendency allowing for the mapping of a sample position in the set and its value, while the second compares the current RSSI to a preconfigured reference value. This article ends with the implementation and testing of the strategy on the ScadaBR Supervisory System.
