Recently, Techworld pointed out the promise of growing
agricultural productivity by adopting IoT-related technologies
[9]. With the literature survey and our experience on developing
IoT systems, previously existing smart farming systems
can be enhanced by employing IoT systems in two aspects: 1)
make it easy to extend systems by allowing new type of devices
to be efficiently and effectively integrated into smart farms; 2)
facilitate horizontal smart farm platforms, which enables all
smart farms to be connected and take advantage of experts’
(i.e., experienced farmers) farming knowledge.
