“…More traditionally, in DDS, this is based on transparent and efficient exploitation of multicast in LAN environments (for instance, for interoperable inter-GCS coordination), with the consequent scalability improvements. However, some emerging DDS solutions [ 18 , 19 ] employ optimized and proprietary pluggable transport protocols for efficient delivery to multiple destinations also in geographic IP-based deployment environments, where the availability of multicast support is often unrealistic. This is relevant for efficiency and scalability motivations, but also to simplify the development and reduce the costs of UAS applications, thanks to the fact that group communication semantic is transparently managed by the DDS middleware, with no impact on the complexity of business logics when integrating complex multi-vendor sub-systems.…”

We claim the strong potential of data-centric communications in Unmanned Aircraft Systems (UAS), as a suitable paradigm to enhance collaborative operations via efficient information sharing, as well as to build systems supporting flexible mission objectives. In particular, this paper analyzes the primary contributions to data dissemination in UAS that can be given by the Data Distribution Service (DDS) open standard, as a solid and industry-mature data-centric technology. Our study is not restricted to traditional UAS where a set of Unmanned Aerial Vehicles (UAVs) transmit data to the ground station that controls them. Instead, we contemplate flexible UAS deployments with multiple UAV units of different sizes and capacities, which are interconnected to form an aerial communication network, enabling the provision of value-added services over a delimited geographical area. In addition, the paper outlines an approach to address the issues inherent to the utilization of network-level multicast, a baseline technology in DDS, in the considered UAS deployments. We complete our analysis with a practical experience aiming at validating the feasibility and the advantages of using DDS in a multi-UAV deployment scenario. For this purpose, we use a UAS testbed built up by heterogeneous hardware equipment, including a number of interconnected micro aerial vehicles, carrying single board computers as payload, as well as real equipment from a tactical UAS from the Spanish Ministry of Defense.

Assuring end-to-end QoS in enterprise distributed real-time and embedded (DRE) systems is hard due to the heterogeneity and transient behavior of communication networks, the lack of integrated mechanisms that schedule communication and computing resources holistically, and the scalability limits of IP multicast in wide-area networks (WANs). This paper makes three contributions to research on overcoming these problems in the context of enterprise DRE systems that use the OMG Data Distribution Service (DDS) quality-ofservice (QoS)-enabled publish/subscribe (pub/sub) middleware over WANs. First, it codifies the limitations of conventional DDS implementations deployed over WANs. Second, it describes a middleware component called Proxy DDS that bridges multiple, isolated DDS domains deployed over WANs. Third, it describes the NetQSIP framework that combines multi-layer, standards-based technologies including the OMG-DDS, Session Initiation Protocol (SIP), and IP DiffServ to support end-to-end QoS in a WAN and shield pub/sub applications from tedious and error-prone details of network QoS mechanisms. The results of experiments using Proxy DDS and NetQSIP show how combining DDS with SIP in DiffServ networks significantly improves dynamic resource reservation in WANs and provides effective end-to-end QoS management.

“…For the inter-domain connection, OMG's DDS provides the Bridging mechanism among the DDS domains [3], but it is only for the domains which are connected to the same network switch. In this regard, it is essential to consider general interdomain networks, which are located far away, to achieve the complete CPS scenario.…”

Abstract-In this paper, we propose the architecture of the Data Distribution Service Gateway (DDS GW) to interconnect different DDS domains for large-scale Cyber-Physical Systems (CPS). We suggest the DDS GW service which runs on the DDS Middleware. It consists of four major components: Interface Module, Topic Manager, Routing Manager and Network Module. We also suggest a basic algorithm for resolving the bottleneck problem caused by the exchanges of EDP messages.
