Summary

Industrial wireless sensor nodes (I-WSNs) have grabbed the attention of researchers all over the world in recent years. One of the major challenges faced by the researchers is the rapid fluctuation of signal due to machinery hindrance, thermal noise and vibration of metal. In an information-theoretic sense, this fluctuation degrades the secrecy capacity of the system in the presence of an eavesdropper.

In this context this paper analyses the outage behavior of an industrial WSN which consists of a multiple sensor nodes and a sink, where data is transmitted over a wireless link. It also proposes the use of sensor scheduling to improve the physical layer security against a malicious eavesdropper, where a sensor with higher secrecy capacity is scheduled to transmit its data to sink. For both the conventional round-robin scheduling and the proposed optimal scheduling schemes, closed-form expressions for the intercept probability are derived.
