The next generation of wireless systems is expected to turn wireless connectivity into a true commodity ``...for anything that may benefit from being connected...'', ranging from tiny wearable sensors to vehicles and drones. A successful implementation of this internet-of-things (IoT) vision calls for a wireless communication system that: (i) is able to support a much larger number of connected devices, (ii) is able to fulfill much more stringent requirements on latency and reliability, and (iii) offers more sophisticated privacy-preserving authentication and security mechanisms. The introduction of future services based on machine-type communication, such as intelligent transportation, augmented reality, remote health care, smart metering, and industrial automation heavily rely on the availability of such a wireless communication system. Indeed all these services require a reliable and low-latency wireless connectivity with strong security and privacy guarantees. The central objective of SEAFRONT is to determine the minimum end-to-end latency that can be guaranteed in wireless communication links where short data packets need to be transmitted with high requirements on reliability, security, and privacy. This is a collaborative project at Chalmers between the Department of Computer Science and Engineering and the Department of Signals and Systems.
