To achieve a cost-effective modern agriculture, a simple, reliable, and manageable routing between the nodes of IoT Robotics networks for precision farming is needed. The focus of this paper is to enhance routing within IoT Robotics networks for precision farming using Software Defined Networking (SDN) technologies.Current routing protocols for IoT robotics solve specific issues each. Some of the issues affecting the nodes are high energy needs and resource constraints. This is as a result of both the controller and data planes of the routing function housed within the same node. SDN routing within IoT Robotics network is proposed in this paper to reduce energyneeds and resource constraints of the nodes as well as to provide simple, reliable and more manageable routing within IoT Robotics networks.
