An engineering approach for secure and safe wireless sensor and actuator networks for industrial automation systems

Abstract

Wireless communication and smart sensors and actuators pose means to sustainably improve automation technology. Unfortunately they also cause an abundance of new challenges regarding security and safety of the system. After introducing the security concepts, this paper discusses an engineering methodology to cope with security requirements in context of industrial automation. Two practical examples demonstrate how the solutions even for pretty similar scenarios can differ significantly. The proposed development flow promises a reliable objective engineering of proper system solutions. Key concepts of the flow are a holistic goal description and an iterative composition algorithm that inherently applies and extends existing knowledge.

An energy aware design flow of distributed industrial wireless sensor and actuator networks

“…Industrial Wireless Sensor and Actuator Network (IWSAN) is a network of not only the sensors but also the actuators which are integrated into the nodes for a variety of applications such as process monitoring, machine statue check and fault detections and it discussed widely in the literatures [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Therefore, each node is capable of having control over its own operation regardless of any central processing unit.…”

Comparison of wireless sensor network and radio frequency identification for the process control of distributed industrial systems

“…Other parameters such as security in manufacturing process, industrial standards and communication protocols have also been discussed and addressed widely in the literature. [9][10][11] RFID systems have also been adopted more recently in the manufacturing and industrial systems. Application of RFID systems in lean manufacturing is given in Weixing et al 12 in order to avoid the bottleneck phenomenon in the production lines.…”
