In this paper we use Ubiquitous Sensor Network(USN) and image information to develop remote navigation system for mobile robot. USN with ultrasonic sensors is used to estimate local position of mobile robot. Using this information of position, mobile robot can navigate in certain area autonomously. And USB web-camera is used to obtain real-time images of remote places and monitor it, when mobil...

Pressure vessels are widely used in industrial fields, and some of them are safety-critical components in the system-for example, those which contain flammable or explosive material. Therefore, the pressure of these vessels becomes one of the critical measurements for operational management. In the paper, we introduce a new approach to the design of non-intrusive pressure sensors, based on ultr...

Electronic canopy characterization is an important issue in tree crop management. Ultrasonic and optical sensors are the most used for this purpose. The objective of this work was to assess the performance of an ultrasonic sensor under laboratory and field conditions in order to provide reliable estimations of distance measurements to apple tree canopies. To this purpose, a methodology has been...

A wireless sensor network consists of spatially distributed autonomous sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants. The development of wireless sensor networks was motivated by military applications such as battlefield surveillance. They are now used in many industrial and civilian application areas...

The process or activity of accurately ascertaining blind's position and planning and following a route in an internal system. Source Localization has been one of the frank setbacks in countless spans, encompassing sonar, radar, teleconferencing or videoconferencing mobile phone locale discovering exploration and globe positioning arrangements localization of earthquake epicenters and undergroun...

Many different wireless sensor nodes for gas pipeline leak detection and location has been proposed but still there are challenges particularly on environmental issues and signal accuracy. This paper discusses theories and environmental constraints for wireless sensor nodes, a case study of Dar es Salaam Tanzania and finally presents a design and simulation results of the proposed wireless sens...

A Wireless Sensor Network (WSN) consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. In sensing applications, data packets are flowing from sensor nodes to base station. In data collection processes, bottom up approach is used. In bottom up approach, all nodes send their sensed data packets to base stati...

A wireless sensor network (WSN) consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure etc. and to cooperatively pass their data through the network to a main location. Transmission of large sized images can be a bottleneck for a Wireless Multimedia Sensor Nodes due to its limited resources. Energy of the indivi...

Wireless Sensor Networks have emerged as one of the leading technologies. These networks are designed to monitor crucial environmental parameters of humidity, temperature, wind speed, soil moisture content, UV index, sound, etc. and then transfer the required information to the base station. However, security remains the key challenge of such networks as critical data is being transferred. Most...
