“…The status of current technology allows the deployment of low power, cost effective network nodes in a battery powered configuration which substitute the traditional wired devices in a very cost effective way [1]. The installation of wireless sensors may give significant cost savings for a variety of typical plants [2]. Current wireless networks for industrial control and monitoring are based on the IEEE 802.15.4 standard [3] and are typically considered for monitoring tasks and supervised/regulatory control.…”

Wireless network technology is becoming a remarkable research topic in the field of industrial monitoring and process control. The widespread adoption of the wireless systems is mandatorily paired with the development of tools for prediction of the wireless link quality to mimic network planning procedures similar to conventional wired systems. In industrial sites the radio signals are prone to blockage due to highly dense metallic structures. The layout of scattering objects from the infrastructure influences the link quality, and thus the strength of the signal power. In this paper it is developed a novel channel model specifically tailored to predict the quality of the radio signal in environments affected by highly dense metallic building blockage. The propagation model is based on the diffraction theory and it makes use of the 3D model of the plant to classify the links based on the number and the density of the obstructions surrounding each link. The proposed channel modeling approach is validated by experimental measurements in two oil refinery sites using industry standard ISA SP100.11a compliant commercial devices operating at 2.4GHz

Wireless networks are particularly vulnerable to spoofing and route poisoning attacks due to the contested transmission medium. Recent works investigate physical layer features such as received signal strength or radio frequency fingerprints to localize and identify malicious devices. In this paper we demonstrate a novel and complementary approach to exploiting physical layer differences among wireless devices that is more energy efficient and invariant with respect to the environment. Specifically, we exploit subtle design differences among transceiver hardware types. Transceivers fulfill the physicallayer aspects of wireless networking protocols, yet specific hardware implementations vary among manufacturers and device types. In this paper we demonstrate that precise manipulation of the physical layer header prevents a subset of transceiver types from receiving the manipulated packet. By soliciting acknowledgments from wireless devices using a small number of packets with manipulated preambles and frame lengths, a response pattern identifies the true transceiver class of the device under test. Herein we demonstrate a transceiver taxonomy of six classes with greater than 99% accuracy, irrespective of environment. We successfully demonstrate wireless multi-factor authentication, intrusion detection, and transceiver type fingerprinting through preamble manipulation.

El uso creciente de las redes Ethernet en el piso de la pirámide de automatización ha hecho que muchas compañías desarrollen dispositivos para operar bajo los requerimientos característicos de este nivel, en la actualidad denominada red Industrial Ethernet, a nivel industrial se encuentra en el mercado variedad de sensores y actuadores que incorporan esta tecnología, muchos de estos equipos se venden a muy alto costo, por eso en este artículo se evaluó el desempeño de dos redes inalámbricas, una con dispositivos del Ethernet convencional, y otra con dispositivos de industrial Ethernet variando cuatro parámetros que son: distancia, número de bytes, relación señal a ruido y la tasa de error de paquetes, midiendo los retardos y comparando con métricas estadísticas los resultados, para ello se usaron graficas Box Plot. Al final, se concluye que bajo los parámetros y condiciones evaluados, las redes inalámbricas pueden servir como sistema de comunicación en aplicaciones de control con retardos permisibles de hasta 50 ms, además, los resultados demuestran un mejor desempeño de las redes industrial Ethernet con respecto a las convencionales, con diferencias en los RTT de milisegundos, por lo tanto, se recomienda establecer qué riesgo representa para el proceso a controlar estos retardos y así determinar si los equipos convencional aplican, ya que bajo ciertas características como condiciones de humedad y temperatura pueden operar adecuadamente durante un tiempo considerable y a un menor costo que los dispositivos de Industrial Ethernet.
