Power consumption, physical size, and architecture design of sensor node processors have been the focus of sensor network research in the architecture community. What lies at the foundation for these research is the hardware- level design which determines the boundaries for achievable utility and performance. Architecture design and evaluation, however, cannot be accomplished independent of the applications and software that run on these sensor nodes. On one hand, some researchers have proposed architectures that can cater to a variety of appli ....etc

ENVIRONMENTAL OBSERVATION AND FORECASTING SYSTEM USING WIRELESS SENSOR NETWORKS

We describe Environmental Observation and Forecasting Systems (EOFS), a new class of large-scale distributed system designed to monitor, model, and forecast wide-area physical processes such as river systems. EOFS have strong social relevance in areas such as education, transportation, agriculture, natural resource planning and disaster response. In addition, they represent an opportunity for scientists to study large physical systems to an extent that ....etc

Abstract
According to the environmental parameters monitoring requirements in greenhouse, a wireless
measurement and control system for temperature and humidity is developed. It overcomes the disadvantages
of wired monitoring system, such as complicated wiring, and difficult maintenance. The environmental
parameters in every greenhouse were measured and controlled by microcontroller.
The hardware and software of the monitoring system are discussed in detail. The experimental results show
that the developed monit ....etc

Wireless distributed microsensor systems will enable fault tolerant monitoring and control of a variety of applications. Due to the large number of microsensor nodes that may be deployed and the long required system lifetimes, replacing the battery is not an option.

Sensor systems must utilize the minimal
possible energy while operating over a wide range of operating scenarios. This paper presents an overview of the key technologies required for low-energy distributed microsensors.

These include
power aware computation/communication ....etc

Environmental noise is a growing priority. Concerns about avi at ion noise have essentially halted airport expansion in large metropolitan areas, which has increased congestion, reduced safety margins, and impacted economic development. Community response to highway traffic noise is beginning to cre at e the same conflict between economic development, safety, and environmental concerns for ground transport at ion systems. Environmental noise is a complex systems problem with significant sociological, physiological, or policy elements as well as ....etc

WISENET is a wireless sensor network

WISENET is a wireless sensor network that monitors the environmental conditions such as light, temperature, and humidity. This network is comprised of nodes called motes that form an ad-hoc network to transmit this data to a computer that function as a server. The server stores the data in a database where it can later be retrieved and analyzed via a web-based interface. The network works successfully with an implementation of one sensor mote.The technological ....etc

Abstract”
In this letter, we analyze a class of Opportunistic Power Allocation (OPA) and sensor selection schemes for parameter estimation in wireless sensor networks. In all cases, only sensors experiencing favorable conditions participate in the estimation process by adjusting their transmit power on the basis of local Channel State Information (CSI) and Residual Energy Information. We address a number of classical problems: the minimization of distortion and transmit power, or the enhancement of network lifetime. Furthermore, we deri ....etc
