Data Aggregation in Internet of Things aiming at Precision Agriculture

Application of Internet of Things (IoT) in agriculture has got attention in recent times. Wireless Sensor Network (WSN) based IoT has been proposed to be deployed in various fields including agriculture. "Routing Protocol for Low Power and Lossy Networks" (RPL) is a standard routing protocol for IoT, proposed in 2012. However, RPL was not designed keeping IoT applications for precision agriculture in mind, and therefore, it needs modification in its design itself, in order to make RPL more suitable for such applications. In this paper, a suitable modification to RPL has been proposed keeping IoT based precision agriculture in mind. The proposed modification suggests a special hierarchical routing structure that leads to energy efficiency. This enhanced form of RPL is scalable and energy efficient. Performance analysis based on analytical model is presented. Future scope of the work is also outlined.
