Experimental Characterization of Wireless Sensor Networks for Industrial Applications

Wireless Sensor Networks in Industrial Automation

“…Especially, when the continuous interference signal exceeds the clear channel assessment (CCA) threshold of the CSMA/CA, the polling task is hindered completely. (Bertocco et al, 2008a) extends the aforementioned study, proposing methods for industrial WSN performance evaluation, and assessing the effect of burst interference on alarm tasks. The interference increased the alarm latencies notably.…”

“…Based on the literature, the area that has gained the most attention (Bertocco et al, 2007); (Vanheel et al, 2008); (Bertocco et al, 2008a); (Bertocco et al, 2008b); (Toscano et al, 2008) is the co-existence of several wireless communication systems in the same ISM band. (Bertocco et al, 2007); (Bertocco et al, 2008a) and (Bertocco et al, 2008b) concentrate on the performance of the CSMA/CA without interferences and in the presence of interferences.…”

“…(Bertocco et al, 2007); (Bertocco et al, 2008a) and (Bertocco et al, 2008b) concentrate on the performance of the CSMA/CA without interferences and in the presence of interferences. In all these papers, the network under study is based on IEEE 802.15.4 and the performance is evaluated both in cyclic polling and in acyclic alarm task.…”

Latency and Packet Loss of an Interferred 802.15.4 Channel in an Industrial Environment

“…15.4 channel that was tested. The latency distribution is also clearly affected by the radio interferences.…”

“…Interesting work has been made by Bertocco and co-workers [15], [16], [17]. Here both some theoretical analysis of 802.15.4 latency paired with some experimental data is given.…”
