Description This building block deals with the run-time coordination and synchronization of wireless sensor networks. It is likely that several heterogeneous wireless technologies are used for communication within a vehicle and for vehicle-to-x communication. On the one hand, these wireless technologies use the same frequency band, resulting in cross- technology interference. SCOTT will investigate coexistence mechanisms to maximize the reliability and efficiency of coexisting networks. On the other hand, SCOTT will explore time synchronization mechanisms amongst different access networks that are suitable for industrial settings. For example, one sensor may use the company’s Wi- Fi to connect to the Internet, whereas another sensor belonging to the same logical application may connect via a cellular network to the Internet. If these sensors are used to measure a specific time sequence of values, it is necessary to synchronize their time.
Main output The main output is to define components, processes and methods to allow system architecture to choose and pick optimal candidates from a collective of technology candidates. For run time support, support like libraries and frameworks will be developed to synchronize operation between technologies, as well as to allow switch-over between alternative technologies
BB category Methodology (for SW/HW development), SW component, Interface, Process
Baseline Baseline of this building block are standardized and state-of-the-art communication protocols for wireless sensor networks (such as IEEE 802.15.4, TSCH, IETF RPL, IEEE 802.15.1, and Bluetooth Smart) as well as time synchronization systems and algorithms for traditional IP networks (e.g., Simple Network Time Protocol, Precision Time Protocol, and Global Positioning System) and tailored to wireless sensor networks (e.g., Reference Broadcast Synchronization, Timing-Sync Protocol for Sensor Networks, Flooding Time Synchronization Protocol, PulseSync, and Glossy).
