A growing trend in the automation industry is to use wireless technologies to reduce cable cost, deployment time, unlocking of stranded information in previously deployed devices, and enabling wireless control applications. Despite a huge research effort in the area of wireless sensor networks (WSNs), there are several issues that have not been addressed properly such that WSNs can be adopted properly...
This paper presents the design and implementation of a wireless monitoring system for building smart room architectures in home environments. The proposed system consists of wireless sensor nodes and actuator nodes which are organized into a monitoring network by ZigBee protocols. A base station and some general wireless nodes have been developed to form a prototype system. Various sensor and actuator...
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...
