“…Therefore, many prompts can be performed inside their own network, for example, distributing information for redirection or temporary storage. The communication between sensor nodes is provided by the DDS (Data Distribution Service) protocol [15]. The message transmission itself is carried out using the request-response method.…”

The article is devoted to the study of existing technologies regarding Internet of Things (IoT) device interaction in a heterogeneous network. Since each smart home appliance can be controlled by a customer who aims to find a cost-effective and easy-to-connect product for their own connected home, there are certain functional limitations for devices from distinct manufacturers that may decrease the intention to merge them all into a single network. A variety of proprietary protocols and communication standards embedded by vendors make their products unable to interact with other vendor devices if the connection standard used is not identical. Also, an IoT product design refers to its own functionality, mainly excluding the possibility of integration into other existing infrastructure. As IoT equipment emerges on the market, the complexity of its connection to a heterogeneous network corresponds to the firmware and the standard unification according to modern demands. It means that potential users might face the necessity of overcoming these issues to achieve high performance in terms of network interoperability. In general, an IoT gateway operating as a middleware might have the potential to enable a network with distinct communication models to operate without failure or data loss. This task requires the received data to be converted into the format in which the data is intended. This paper includes a comparative analysis of existing IoT device interaction standards, connection protocols, and data transfer technologies, evaluating their features for an effective adoption of the proposed network architecture, which can be used to improve the interoperability of heterogeneous IoT devices.

“…Security enhancements in ROS2 include authentication of nodes joining the DDS domain and encryption of data transmitted through ROS2 topics. DDS enables deployment of companion computers that use real-time operating systems, with potential to further reduce latency and improve synchronization [9,11,24,25].…”

Real-time flight controllers are becoming dependent on general-purpose operating systems, as the modularity and complexity of guidance, navigation, and control systems and algorithms increases. The non-deterministic nature of operating systems creates a critical weakness in the development of motion control systems for robotic platforms due to the random delays introduced by operating systems and communication networks. The high-speed operation and sensitive dynamics of UAVs demand fast and near-deterministic communication between the sensors, companion computer, and flight control unit (FCU) in order to achieve the required performance. In this paper, we present a method to assess communications latency between a companion computer and an RTOS open-source flight controller, which is based on an XRCE-DDS bridge between clients hosted in the low-resource environment and the DDS network used by ROS2. A comparison based on the measured statistics of latency illustrates the advantages of XRCE-DDS compared to the standard communication method based on MAVROS-MAVLink. More importantly, an algorithm to estimate latency offset and clock skew based on an exponential moving average filter is presented, providing a tool for latency estimation and correction that can be used by developers to improve synchronization of processes that rely on timely communication between the FCU and companion computer, such as synchronization of lower-level sensor data at the higher-level layer. This addresses the challenges introduced in GNC applications by the non-deterministic nature of general-purpose operating systems and the inherent limitations of standard flight controller hardware.

“…Additionally, DDS offers various Quality of Service (QoS) policies that permit publishers and subscribers to define the preferred method of data transfer, including aspects like reliability, response time, and throughput. DDS is used as the messaging protocol in variety of IoT systems such as Industrial automation systems, healthcare, smart grid systems, autonomous vehicles and unmanned aerial vehicles (UAVs) [29].…”

IoT is a technological ecosystem that improves people's daily lives by improving productivity, safety, comfort, health, wellness and sustainability. In addition, IoT offers various benefits to different industries such as improved efficiency, productivity and cost savings. However, the increase in the use of IoT has revealed many security vulnerabilities, especially the middleware layer. In this article, we presented possible attacks on availability of middleware layer messaging protocols. We specifically focused on MQTT protocol and conducted a case study. MitM, DoS and BruteForce attacks were carried out in the test environment, the results were shared and the measures to be taken against the attacks were discussed.
