“…Several methodologies which allow connecting IoT components in communication networks without human innovation were described. Unfortunately, they still can have limitations in real-time interactions, such as unstable work in the network [132]. Regardless, the Internet or IoT, the advanced communication technologies, and modern AI tools used in robotics have a promising future [36].…”

Recent years have seen a rapid development of the Internet of Things (IoT) and the growth of autonomous robotic applications which are using network communications. Accordingly, an increasing advancement of intelligent devices with wireless sensors (that means autonomous robotic platforms) operating in challenging environments makes robots a tangible reality in the near future. Unfortunately, as a result of technical development, security problems emerge, especially when considering human–robot collaboration. Two abnormalities often compromise the basic security of collaborative robotic fleets: (a) Information faults and (b) system failures. This paper attempts to describe the methodology of a control framework design for secure robotic systems aided by the Internet of Things. The suggested concept represents a control system structure using blocks as the components. The structure is designed for the robots expected to interact with humans safely and act connected by communication channels. The properties of the components and relations between them are briefly described. The novelty of the proposed concept concerns the security mechanisms. The paper also categorizes two different modes of network attacks summarizing their causal effects on the human–robot collaboration systems. The issue of standardization is also raised. In particular, the works of the National Institute of Standards and Technology (NIST) and European Parliament (EP) on the security templates for communication channels are commented.

“…The use of IoT-Stream/SOSA and IoT-Lite ontologies helps in the identification of data streams with the semantic information provided. While for IoT-Stream, the authors suggest the use of MQTT servers, we proposed a more elaborated resource than that provided by the Software Real-Time Interaction Protocol (SRTI) [32].…”

“…Based on this information, upper layers services within the IoT model can request data or information from them. The public directory is managed by brokers within the network that can share data using, e.g., the MQTT extension (as proposed in [32]). Note that the taxonomic ID corresponding to every record in Table 1 is displayed using 4-value notation (corresponding to the different sections associated with a sensor's ID).…”

IoT-based applications will be able to subscribe to particular sensors, invoking the analytic service in order to solve different problems.…”

Sustainable cities aim to have a lower environmental impact by reducing their carbon footprints as much as possible. The smart city paradigm based on the Internet of Things (IoT) is the natural approach to achieving this goal. Nevertheless, the proliferation of sensors and IoT technologies, along with the need for annotating real-time data, has promoted the need for light weight ontology-based models for IoT environments, such as IoT-Stream. The IoT-Stream model takes advantage of common knowledge sharing of the semantics while keeping queries and inferences simple. However, sensors in the IoT-Stream model are conceptualized as single entities, exluding further analysis concerning their features (energy consumption, cost, etc.) or application areas. In this article, we present a taxonomy of sensors that expands the original IoT-Stream model by facilitating the mapping of sensors/actuators and services in the context of smart cities in such a way that different applications can share information in a transparent way, avoiding unnecessary duplication of sensors and network infrastructure.

“…In order to reduce the traffic through the backhaul in IoRT systems, the next section describes the proposed extension to LoRaWAN (i.e., NA-LoRaWAN). This extension is based on a previous work, where the authors proposed an agent that processed packets in an intermediate node [ 24 ], i.e., after the packet had been sent by the source node, and before sending it at the destination. This agent was able to filter, aggregate or transform data dynamically.…”

Reducing Operational Expenses of LoRaWAN-Based Internet of Remote Things Applications

LoRaWAN has become the most widely used low-power wide-area network technology to implement monitoring solutions based on the Internet of remote things (IoRT) paradigm. Typically, these solutions interconnect remote sensing areas and data processing infrastructure located in urban centers. The operation expenses of these solutions depend mainly on the traffic sent through the network backhaul, i.e., the link that connects the remote sensing area and the urban area where the data are usually processed and stored. This service is provided by telecommunication companies and represents the main operation cost of IoRT solutions. These expenses usually limit the affordability of IoRT-based systems in developing countries, and also in scenarios where the operational cost is an issue to address. This paper presents an extension to the LoRaWAN protocol, named Node-Aware-LoRaWAN (NA-LoRaWAN), that reduces the traffic in the backhaul, thus decreasing the operational expenses of IoRT-based systems. In order to evaluate the performance of NA-LoRaWAN, it was compared to a regular LoRaWAN implementation. Depending on the network scenario, the proposed extension reduced the traffic through the backhaul in the range of 12–34%. This extension opens several opportunities to use IoRT solutions in application domains with a low operational budget, e.g., precision agriculture, environmental monitoring and natural hazards’ early detection.
