Wireless sensor networks (WSNs) have been adopted as merely data producers for years. However, the data collected by WSNs can also be used to manage their operation and avoid unnecessary measurements that do not provide any new knowledge about the environment. The benefits are twofold because wireless sensor nodes may save their limited energy resources and also reduce the wireless medium occupancy...
The one of the major difficulties in deploying a wireless sensor to monitor debris flow in the real world is power consumption. Frequently replacing the battery of a sensor that is located in a remote mountainous area is not practical. In this study we examine the newly-introduced wireless debris flow sensor, SMARTCONE, which is designed to minimize the standby power consumption, but still keep alert...
Use of wireless technology is applicable in most of area in information and communication technology (ICT). Rapid growth of user and devices make provider have difficulties to handle large data traffic in current system. Provider has to setup large size data center (server) to accommodate increasing number of user and data. Stability and availability of data center need to be on all the time, thus...
The use of a Wireless Sensor Network (WSN) has increased in the last years in many different fields. One of the main advantages of WSNs is the fast data acquisition thanks to the data gathering systems that can archive, process and send the collected data through Internet or store them in different formats. These data archiving and processing is very useful for water quality monitoring. The monitoring...
In this paper we present an ambient intelligence system for modelling and control of power use within an office environment. We define a multi-scale model of the office worker, consisting of a coarse grained office user profile, together with a fine grained characteristics model to summarise their behaviours. Sensor data gathered from individual offices are used to create these models. Collected data...
The two most important objectives of the data center operators are to reduce operating cost and minimize carbon emission. Consolidation of data centers is not always possible and big enterprise end up having data centers in multiple locations across different cities and countries. In such a diverse deployment manual monitoring is not a cost effective solution. ASHRAE [1] suggested considering the...
In the last years the demographic changes and ageing of population increase health care demand. Increasing number of chronic patients and elders requires close attention to their health conditions. In this paper we present the realization of a wireless monitoring system capable to measure process and transmit patient's physiologic signals (electrocardiogram, respiratory rhythm, arterial saturation...
As the switch contacts and the bus are in high voltage, each Phase-to-ground and different phase has high voltage, monitoring of high voltage switchgear electrical junction temperature is always a difficult problem. Face this Special working environment, ZigBee wireless transmission technology can complete the wireless signal transmission channel, solve the high-voltage sensor modules; power supply...
The monitoring of heat generation inside closed high-voltage switch cabinet is a technical problem which affects safe production at present. This paper analyses the present early warning technique for switch cabinet at home and abroad and proposes the high-voltage switch cabinet elements based on gas composition analysis, and deeply analyses the principle of temperature measurement using laser light...
Temperature measurement and monitoring plays a very important role in cold chain of blood. This paper describes a Web-based real-time monitoring system on cold chain of blood. The objective is split into three different tasks. First, wireless sensors send sensing data to database server through two types of networks: 1) For outdoor network, wireless sensors on mobile devices send data through the...
Water quality monitoring plays an important role in modern intensive fish farming management. In order to improve the efficiency and precision of the data collection procedure, it is necessary to have an automated monitoring system that collects environmental data, especially to record long-term and up-to-the-minute environmental fluctuations. The purpose of this research was to design a remote-controlled,...
In case of simulation games to grow an avatar using mobile devices such as cellular phone, the main trend was download type games because of expensive communication cost. However, in those download type games, the interoperability between WEB and WAP was not easy. Thus we propose the platform design to develop serious games playable in wired and wireless environments with WAP Push technology.
