Implementing and testing of IoT technology in agriculture

Abstract

Agriculture involves various physical quantities that need to be monitored and controlled. IoT have several capabilities which are suitable for implementing Precise Agriculture. IoT architecture involves sensors, nodes and computing which can be edge, fog and cloud computing. In IoT there has been a need of communication between nodes, nodes and gateway and gateways to cloud. Different protocols are used at different layers of IoT architecture for communication. Those must be analysed for selecting appropriate protocol for an application. As IoT uses low power devices resources must be utilized properly. There has been a need of low bandwidth, low power communication protocols both in application and network layers to support heavy traffic in power constrained devices. In this paper detailed comparison is made between application layer protocols used in IoT namely MQTT and HTTP for their suitability in IoT applications.
