Real-time networks for substations automation systems are based on ICT technologies and they may take great advantages from ultra recent network technological improvements. A careful evaluation of the performance enhancement is required. Due to cost and system complexity, such an analysis can be performed only using a dedicated simulation environment, but the currently available simulation libraries...
Today, wireless sensor technology is based on monolithic transceivers that optimize cost but have a rigid hardware architecture. In this paper, a new architecture for wireless sensors is presented. It is based on a software-defined radio concept and shows impressive adaptability to external conditions. The proposed architecture, which is called the wireless ultrasmart sensor (WUSS), enables the use...
Wireless Sensor Networks (WSN) are used in a great number of applications. Unfortunately the programming of each node is till now a problem that limits the diffusion of this technology in commercial applications. In fact, in order to meet the strict requirements of the WSN, such as power optimization, specific operative systems (TinyOS) and programming languages have been used. On the contrary, the...
Traditional wireless sensors rely on monolithic transceivers optimizing cost but offering a very low flexibility. On the other hand, microwaves in the GHz range are used for displacement and position sensing. In this work a new architecture for wireless sensors, called wireless ultra smart sensor, is introduced. The new sensor architecture is built using software defined radio concepts and it has...
