# IoT-Enabled Precision Agriculture: Developing an Ecosystem for Optimized Crop Management
## 3 Overview of Precision Agriculture
### The Proposed System Model  
This paper provides a reference framework to facilitate the development of precision agriculture applications. The proposed model considers heterogeneous sensors and network-enabling technologies for near-real-time network access to status information about a pool of agricultural resources. These resources include trees, animals, water pumps, applications, and other services. These resources can be controlled with minimal management effort or farmer interaction. By using this system, farmers can benefit in multiple ways:  
1. Real-time monitoring: The proposed system allows farmers to monitor their crops and livestock in real time, which enables them to take prompt action in case of any abnormalities or issues. 2. Automated decision making: The system uses data analysis to provide farmers with insights and recommendations for optimizing their operations, such as determining the ideal time for planting or harvesting or identifying the best feeding and watering schedule for their livestock. 3. Reduced labor costs: The system allows farmers to automate many of their tasks, such as irrigation and pest control, which reduces the need for labor-intensive manual work. 4. Improved crop and animal health: The system allows farmers to monitor the health of their crops and animals more closely, which enables them to identify and address issues more quickly. 5. Increased yield and revenue: By using precision agriculture techniques, farmers can improve their crop yields and animal health, leading to increased revenue. 6. Resource optimization: The proposed system can also help farmers optimize their use of resources, such as water and fertilizers, which can reduce costs and minimize environmental impact. The proposed system model for precision agriculture comprises three main layers, as shown in Figure 1: devices and platforms, communication layers, and application layers. 1. The application layer includes user applications, data analysis, and dashboards used to monitor and optimize precision operations. The Big Data and analytics module consist of a data warehouse storage, which runs at the application layer. This component contains the technology and services necessary to integrate and archive data from multiple sensors and applications, enabling the IoT system to derive and deliver value from its data assets. 2. The communication layer offers real-time connectivity and enables communication between devices and platforms. This includes sensors to sensors, sensors to gateways, and gateways to servers within the IoT ecosystem. The framework combines several heterogeneous communication technologies, such as IEEE 802.4.15, 6 lowPAN, and COAP. 3. The devices and platforms layer is the foundation of the IoT ecosystem infrastructure. These layers include system components such as sensors, gateways, and server platforms. Sensors are devices that capture the status information about physical world objects and convert them into digital data for transmission and processing. The main goal of the gateway's platform is to aggregate heterogeneous data sources with different communication standards, given that an array of sensor devices is required to collect data about plants, water, environments, animals, and soil, among others. Servers host user applications and data repositories and provide unified access APIs for other systems and users. The three main layers of the proposed system model, devices and platforms, communication layers, and application layers, interact to perform the high-level operations of precision agriculture. The devices and platforms layer is the foundation of the IoT ecosystem infrastructure, including system components such as sensors, gateways, and server platforms. These devices capture the status information about physical world objects and convert them into digital data for transmission and processing.
