In a smart home, the home status, as well as the human activities, can be observed through a number of sensors. A wireless network can transfer the data to an information system and the commands from the information system to the sensors and actuators. In small areas such as smart homes, four types of noise may form in communication system. In this work, we explore how the noise can be resolved by...
Indoor wireless transceivers connect sensors and actuators, which are carried by a mobile agent to the Smart Home Information System (SHIS). In the smart home, the sensors' role is to observe the human activities and home status, while the actuators are to perform assistive and recovery actions for serving the home resident. The SHIS then analyzes the sensors' data and issues the actuation commands...

The proposed system has high availability and reliability. It could meet the requirements of daily life such as the control...
The emergence of, and advancement in, integrated digital circuitry technology along with the development of efficient software algorithms made it possible to build small, lightweight wireless nodes equipped with embedded processors, sensors and radio transceivers. By densely deploying these nodes, in a highly distributed manner, we can build a Wireless Sensor Network (WSN). In this network, sensors...
The paper presents the interface designed for wireless data and power transmission. The interface operation idea was tested using build up hardware and software. The sample construction of the temperature sensor embedded with this type interface was designed. Measurements show that the sensor can be wirelessly supplied with energy and is capable to sent data (temperature readings) in 5 cm distance...
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...
With the latest advances in wireless communication, new monitoring and supervisory control tools have been designed for industrial systems, avoiding unexpected failures and greatly improving system reliability and maintainability. Usually supervisory control for electric systems applies wireless sensor networks (WSN). WSN comprises many sensor nodes each one containing a processing unit, one or more...
Body sensor network (BSN) is a wireless network of implantable and/or wearable smart sensors. They can be deployed in medical applications, such as patients monitoring inside or outside hospital environment, as well as in high performance professional sports and other non human related applications. The size of a sensor node and its power consumption are major challenges in the design of implantable...
On the basis of the Programmable System-on-Chip (PSoC) and thin-film MEMS structure the Smart Pressure Sensor was developed by using newest method of definition of gas pressure. This sensor have such advantages before analogues as high accuracy of transformation, stability of characteristics, durability, presence of a set of standard digital and wireless interfaces. On the basis of one chip PSoC all...

In this paper, a new concept for a very flexible and modular prototype platform for rapid prototyping of wireless sensor networks is presented. We propose to use a FPGA with high gate count as core of the platform. The FPGA is utilized to attain 3 major goals for the prototype platform: to emulate arbitrary mote architectures even including smart motes with high system complexity, to realize flexible...
The presented analysis shows that a system approach, that targets heterogeneous technologies, is clearly needed to address ultra-low power operation of hardware built for wireless sensor networks. CMOS design efforts have to be aided by a clear understanding of network requirements and protocol implementation. A very talented CMOS designer, or even dozen of them, working in isolation are not going...
A scale model of a tractor-trailer truck was developed as a testbed for control algorithms. The truck operates in autonomous or semi-autonomous modes. An on-board Pentium computer with a PC104 bus performs the computations and data collection. Various sensors and a wireless transceiver are on-board the truck. Our research focus has been in the autonomous control of vehicles using intelligent systems...
