“…The M2M communications within our WSN are implemented by a protocol stack (illustrated in Figure 4) specifically designed to satisfy the SheepIT requirements [22,24]. Despite having this particular project in mind, the stack design was driven by more general goals, aggregating the traffic requirements of several applications related to farming management and supervision.…”

“…To evaluate the feasibility of the proposed solution, we need to demonstrate that our approach complies with all identified requirements. In [22] the requirements and design of the communication mechanism, especially regarding the Physical and MAC Layers were addressed and theoretically evaluated. This evaluation included the validation of timing and energy consumption constraints, being demonstrated by the theoretical feasibility of our approach.…”

“…Additionally, SheepIT exhibits a few distinctive requirements that, when combined with the aforementioned ones, preclude the use of existing IoT solutions. The complete and detailed set of requirements can be found in [22], but they can be briefly summarized as follows:The presence of irregular slopes with several obstacles;Unforeseeable node mobility (sheep);Variable node densities due to the flock movement;Need for real-time localization, preferably resorting to Received Signal Strength Indicator (RSSI)-based localization;Need to ensure the coexistence of an effective control posture mechanism;Frequent system reconfigurations by non-technical personnel.…”

“…In order to fulfill these needs, an architecture was designed composed by a Wireless Sensor Network (WSN) [22] and a Computational Platform (CP) [23] accessible via the Internet. The WSN comprises a set of instrumented mobile nodes carried by sheep (collars); a set of statically placed nodes for defining the grazing area and collect sheep’s data (beacons); and a gateway that, besides connecting the WSN to the CP, delivers local services.…”

Intelligent farming is one of the vast range of applications covered by the Internet of Things concept. Notwithstanding, such applications present specific requirements and constraints that are dependent on their purpose. A practical case on which that is particularly relevant is the SheepIT project, where an automated IoT-based system controls grazing sheep within vineyards, guaranteeing that they do not threaten cultures. Due to its rigid requirements, particularly regarding the deployment of the Wireless Sensor Network, Machine-2-Machine communications and necessary interactions with a computational platform available through the Internet, Internet Protocol-based solutions are not suitable. Consequently, a customized communication stack has been developed, that intends to meet the project requirements, from the physical to the Application Layers. Although it has been developed considering the SheepIT requirements, its use may be extended to more generic intelligent farming applications, since most of the requirements are directly related with the farming environment. This paper reviews the proposed stack and details the recent developments. Particularly, we focused on Internet of Things/Machine-2-Machine interaction, describing the design and deployment of a gateway that addresses the SheepIT service requirements. Additionally, and complementary to previously published results, we evaluate the gateway performance and show its feasibility and scalability in a real scenario.
