'MULTIFUNCTIONAL GATEWAY SENSOR NODE IN WIRELESS SENSOR NETWORK FOR AGRICULTURAL AND FOREST ACTIVITIES

摘要

The Multifunctional Gateway Sensor Node is an extension of the Gateway sensor node of Wireless Sensor Network having multiple functionalities. Addendum of functionalities comprise different types of technologies which are LCD Color display, keypad to operate Gateway Node, AVR camera and solar panel for additional power support. The node itself also acts as a weather station based on Fuzzy AHP for precise decision support. So the main idea behind this is to operate WSN without computer. It will be most usable in agriculture, forest monitoring as well as marine securities when pc is unavailable. The location of particular place for weather station feature will be selected by the help of Koppen Classification, instead of GPS. This sensor node is also operable by the specially designed Java based software having great intelligence as per the locality. These sensors reads the data on the farm field and send it to radio base station connected to computer and generate the graphical data of the field. And also using the Arial images of the farm the NDVI (Normalized Difference Vegetation Index) images will help to locate the precise location of the Weeds and also useful in monitoring of the crop in the field. All this controlling option is supported by the Atmospheric weather forecasting for taking smart and precise decision for the particular crop on particular season at particular time. System also uses the geographical location of the field and will help farmer for taking the suitable crop of combination of it. All these features can be operable anywhere and anytime in the world even also by using SMS services.
