Security and Performance Trade-offs for Data Distribution Service in Flying Ad-Hoc Networks

Abstract

This paper focuses on the data distribution service (DDS) middleware and its publish/subscribe logic-a topic that has recently regained popularity in both academia as well as industry. DDS is a well-known approach based on publishsubscribe logic. Therefore, only brief introduction of the issue is given followed by practical evaluation of current, available and real implementations from the security and performance point of view. The analysis and evaluation is performed to aid comparison of competing DDS implementation, and thus could serve well as an input to decision-making about which of these solutions is best suited for a given situation. Finally, the practical performance evaluation is performed via several different scenarios to effectively compare the currently most-used DDS implementations.

“…After comparing the three popular DDS open source implementations, OpenDDS performs better than OpenSplice and Fast-RTPS in terms of latency and jitter. Radek Fujdiak et al [7] moreover, they evaluate not only performance, but also the security characteristics of each DDS implementation. In order to balance safety and efficiency, we choose OpenDDS because it is great in terms of performance and data security in OpenDDS is guaranteed.…”
