Wireless sensor networks (WSNs) have been the focus of many research works. Nowadays, because of the time-critical tasks of several WSN applications, one of the new challenges faced by WSNs is handling real-time storage and querying the data they process. This is the real-time database management on WSN and it deals with time-constrained data, time-constrained transactions, and limited resource...

Scheduling decisions in time-critical systems are very difficult, due to the vast number of systems’ parameters and tasks’ attributes involved in such decisions. Due to the intractability of the problem, time-critical systems often have to resort to heuristic techniques. Value-based scheduling heuristics have been found in the literature to experience a more graceful degradation under overload ...

Real-time extensions to standard switched Ethernet widen the realm of computer networking into the time-critical domain. These technologies have started to establish in process automation, while Ethernet-based communication infrastructures in vehicles are novel and challenged by particularly hard real-time constraints. Simulation tools are of vital importance to explore the technical feasibilit...

Acoustic feedback offers promising opportunities to enhance the perception of athletes in regards of the modification of movement patterns and control in technique training. Sound conveys time-critical structures that are perceived subliminally, which is of crucial importance for the precision when modifying movements to improve their execution. Technological advances allow the design of innova...
