Design and Development of a Simulation Frame Work for WSN Based Moisture Deficit Monitoring and Control in Irrigated Agriculture

Abstract

The dependency of economy of many countries on irrigated agriculture demand a high level precision in water supply and regulation to save water and incurred cost. The technology of Wireless Sensor Networks (WSN) seems to give a possible solution for this. However before such technologies are applied we need to have simulating environment and tools to foresee the strategies of implementations. There are some simulators available that help to simulate various networks. However for simulating Moisture Deficit Monitoring and Control in Irrigated Agriculture, there is a need to for typically designed and developed simulation application framework. This paper presents a complete simulation application framework created in ns2 simulation environment considering all parameters and possibilities. A WSN cluster-based approach is used for the simulation. The class hierarchy is developed and tested with tcl scripts of ns2. It deals with sensed soil moisture data, its routing, aggregation, Processing and relay to the sink. Both On Demand and Event based approaches are taken in consideration. The application will finally give a real situation of soil moisture and distribution in the field and will help in quantifying the supply and irrigation scheduling.
