Joël Goossens receives an Influential Papers Award in the framework of the 25th anniversary of the International Conference on Real-Time Networks and Systems RTNS 2017. The awarded paper is entitled “Limitation of the hyper-period in real-time periodic task set generation”. The research presents a method to generate arbitrary and randomly periodic real-time tasks.

The originality of the method relays on the smart way to choose the task periods in order to reduce the hyper-period of the system. This result speedups the timing analysis validation and verification phase in the design of real-time system, by reducing the length of the observation interval.
