The area of sensor network has a long history and many kind of sensor devices are used in various real life applications. Here, we introduce Wireless sensor network which when combine with other areas then plays an important role in analyzing the data of forest temperature, bioinformatics, water contamination, traffic control, telecommunication etc. Due to the advancement in the area of wireless sensor...
This paper shows the use of data warehouse as an alternative for managing data collected by Wireless Sensor Networks that monitor bees. The scientific research that uses Wireless Sensor Network for habitat or animal monitor used to produce a large amount of data that need to be analyzed and normalized, so as to help researchers and other people interested in the information. These data managed and...
Wireless sensor networks (WSN) typically consist of compact, low energy devices capable of sustaining a variety of ad-hoc topologies and operate for many years from a single, non-renewable, finite energy source such as a battery. This limitation in energy has led to much research in the field of energy conservation both through hardware and software techniques. The transmission of data incurs the...
This paper addresses the clock synchronization problem in a wireless sensor network (WSN) and proposes a distributed solution that consists of a form of consensus, where agents are able to exchange data representing intervals or sets. The solution is based on a centralized algorithm for clock synchronization, proposed by Marzullo, that determines the smallest interval that is in common with the maximum...
Sensor networks have been deployed for a range of rural and environmental applications. Well-regarded for the volume and range of data which can be obtained, wireless sensor network applications capable of using the data gathered have not been fully realized, particularly in urban settings. Street CORNERS is a wireless sensor network application which supports the contextual presentation of data gathered...
This paper proposed a portable wireless data acquisition system for temperature in real time process dynamics. Process variables (like temperature, pressure, flow, level) vary with time in certain applications and this variation should be recorded so that a control action can take place at a defined set point. This paper proposes an 8 bit embedded platform for a sensor having a network interface using...
