Design of a Long Range Wireless Sensor Network in Agriculture for Precision Irrigation

Efficient and low power utilizing data synchronization is a challenging task for a Wireless-Sensor Network (WSN). Therefore, it is crucial to design a lightweight data synchronization protocols for these networks. An adaptive data offset prediction model for WSN is proposed in this project that exchanges fewer synchronization messages to improve the accuracy and efficiency. The proposed model is based on a tailored hardware and software aiming to extend both sensor nodes and WSN lifetime. The coordinator is aware of its sensor nodes available energy and such feature enables estimating the remaining lifetime of each sensor node. The sensor node system for data acquisition of long range is the conceptual model for a sensor node hardware and software system design, concerning energy management improving both sensor nodes and network lifetime .The experimental sensor nodes were employed to monitor soil moisture , temperature ,humidity and light sensor also the base station system model will validate in field conditions.
