Wireless Sensor Networks for Environmental Monitoring

The paper is concerned with the applications of Wireless Sensor Network (WSN) technology for large scale and long duration environmental monitoring. We illustrate here the technological difficulties and challenges that have been encountered in meeting end-users requirements for information gathering. The main aim is to provide greater reliability and productivity to influence the design choices of system hardware and software. WSN technology can be used for various large scale monitoring purposes, providing sensor measurements at high resolution. This technology, therefore, provides various information regarding different monitoring applications such as forests, waterways, buildings, security, agriculture, battlefield etc. Wireless Sensor Networks (WSNs) can also perform operations such as event detection, aggregation, sensing and actuation. We conclude with the discussion of long-term environmental monitoring using WSN technology. Considering future challenges and opportunities our objective is to provide the applications of WSN technology in the field of environmental and agricultural monitoring.
