3. WSN Scope  Over the last decade, wireless sensor networks (WSNs) have attracted a lot of attention from the research community.  With hundreds or thousands of sensor nodes, a WSN must employ distributed algorithms to support its applications.

4.  These algorithms must be highly localized as long distance transmissions are very expensive, and would diminish the network's overall lifespan.  WSN must be self-configurable, highly scalable, redundant, and robust. WSN Scope

5.  The features of WSNs can be applied to a variety of applications for environmental for example :  (agriculture, water, forest) monitoring.  battle field surveillance.  health (e.g., elderly people) monitoring.  and industry process control. WSN Scope

6.  In the near future. For instance, disaster relief applications can provide an effective system to detect living human beings to help successfully manage a disaster relief operation, potentially saving hundreds of lives. WSN Scope

7. Wireless Solutions

8.  A WSN is a collection of nodes with  low performance CPU,  memory,  radio transmitter  and sensors.  They make environmental measurements (sensing) and transmit them to a collection point, which then forwards them to a remote processing system.

9. Wireless Solutions  The characteristic of these nodes is that they are  small,  low-power,  wirelessly interconnected  and cost-effective.  The network form has the characteristic of being self-configuring and autonomous, requiring no human intervention, can cover a very large area and can remain active for a long time.

10. Wireless Solutions  Solutions based on WSN saves  a lot on costs,  monitor much larger areas with extreme environmental conditions and in places very narrow and difficult to reach. Moreover, given the low cost of each node are used in emergency situations where they may be destroyed or lost in some way, such as in areas at risk of fire or landslides.

11. Precision Agriculture

12.  Vineyards and Greenhouses  In this context, the sensors network is used to monitor environmental parameters of crop cultivation, so that the farmer knows, for example, when having water or when to use certain pesticides. Thanks to combination of sensors such as humidity, temperature, and light and so on.  Avoid the risk of frost, as well as any plant diseases or you can control the level of irrigation based on soil moisture and leaf wetness.

13. IMPLICATIONS OF HOT POTATOES  The precision agriculture has the ‘aim of  optimizing the production,  taking into account local soil and climatic variations.  All this involves extremely precise control of vital parameters for vineyards and greenhouses, so that irrigation and climate control correspond to local conditions.

15.  In the greenhouses solar radiation:  temperature and CO2 concentration are correlated to determine the final production.  If any of these factors is limiting, it becomes unnecessary to increase the other. Precision Agriculture

16.  The main factors of the microclimate in the greenhouse that we can control and manage are:  Temperature, CO2 concentration,  Humidity,  Intensity of radiation  and wind pressure or speed. Precision Agriculture
