This paper proposes a new time synchronization algorithm for wireless sensor networks, named clustered consensus time synchronization (CCTS). This algorithm is developed on the base of the distributed consensus time synchronization (DCTS) algorithm. However, to obtain faster convergence in the clock synchronization of node and better energy efficiency, the clustering technique is incorporated into...
Clock/time-driven models are powerful abstractions of real-time systems, as e.g., provided by the synchronous models of computation which lend themselves well for simulation and verification. At every clock cycle, new inputs are read, computations are performed in zero-time, and results are immediately/synchronously communicated between components. However, such zero-time idealizations are not realistic...
While synchronous system models have many advantages over asynchronous models concerning verification and validation, many implementation platforms do not provide efficient means for synchronization. For this reason, we consider a design flow that starts with a synchronous system model that is then transformed into an asynchronous one for synthesis. In essence, it partitions the synchronous system...
The synchronous programming model is perfect for modeling, simulation, verification and implementation of reactive systems. While this paradigm can be directly implemented as hardware circuits, multithreaded software implementations are typically based on asynchronous threads. For this reason, an efficient multithreaded software implementation of a synchronous program requires a so-called desynchronization...
