Nowadays the Internet plays an important role in people's daily-life. We all witness the great success of different practical networked systems. HotPNS seeks contributions that are relevant to solve practical computer networking and protocol problems. Prospective topics include network sciences, Internet of Things (IoT), cyber-physical systems, data mining of large scale networks, and security/privacy issues. Authors are encouraged to submit papers describing original, previously unpublished research, not currently under review by another conference or journal, addressing state-of-the-art research and development in all areas of practical networked systems.
