Monitoring Area - Introduction to Wireless Sensor Networks
Example: Precision Agriculture - Precision agriculture aims at making cultural operations more efficient, while reducing environmental impact.
- The information collected from sensors is used to evaluate optimum sowing density, estimate fertilizers and other inputs needs, and to more accurately predict crop yields.

- Introduction to Wireless Sensor Networks
- Wireless Sensor Networks mainly consists of sensors. Sensors are -
- low power
- limited memory
- energy constrained due to their small size.
- Wireless networks can also be deployed in extreme environmental conditions and may be prone to enemy attacks.
- Although deployed in an ad hoc manner they need to be self organized and self healing and can face constant reconfiguration.
