Wireless sensor networks have to be very flexible and self-configuring, providing an easy way to be deployed. This is a feature that is required due to a wide spectrum of possible applications and deployment scenarios in which they can be used. They can support different kinds of tools and applications in distinct areas, such as agriculture, military, health care, home or industry automation and others...
Temperature, humidity and light condition of greenhouses is related to the growth of vegetables. How to adjust temperature, humidity and light conditions is scientifically and rationally. Its benefit for vegetables are mature, high-quality and efficiency. Therefore, obtain timely and accurate information will improve the yield and quality of vegetables. Greenhouses vegetable environmental characteristics,...
The wireless sensor networks (WSN) is one of the most significant technologies in the 21st century. In recent years, achievements in micro-sensor technology and low-power electronics make WSN become realities in applications. In this paper, we propose a system for WSN based on environmental monitoring. The system can monitor several environmental parameters such as underground water level, barometric...
This paper addresses how to exploit temporal and spatial data correlations to collect data energy-efficiently from sensor nodes. In our approach, models are maintained by nodes and cluster heads, and replica models are maintained by the base station. The base station uses the replica models to estimate the actual measurement data in usual time, and an actual measurement datum is sent to the base station...
