Today progress of artificial intelligence science in the different sciences specially agricultural sciences is be very important. If there is not specific relationship between effective factors for creating of a phenomenon, it appears. The reference evapotranspiration is a phenomenon that experimental relationships for calculating of it has be expressed up to now. Using of these relationships requires complicated calculations and more important than all requires calibration for every region. Accuracy of these relationships varies in according to climate and studying region position. We have modeled and predicted values of reference evapotranspiration for grass plant of a farm in Mo′tamediyeh village located Neishabour town by using of artificial neural network in the research. The results of the research in addition to high compatibility of modeling and predicting with correlation coefficient 0.997 can analyze sensitivity and affecting every parameters of effective of the grass reference evapotranspiration values.

Today by more complicating in smart grid, request and need for reliability, security and more efficiency and also environmental concerns, we need to change the operation and use of electrical networks. Power companies and the government consider that the smart grid will be salvation for the future. Recent advances in the fabrication of integrated circuits and the development of wireless communication technology that is cusses WSN entry in smart grid. One of the most important features of sensor networks used in smart grid is the energy constraints. So we will offer a new architecture for smart grid in the field of the WSNs to reduce the total energy. Moreover, we will improve some routing factors, Qo S parameters such as delay and reliability with respect to the desired user.
