An Effective Synchronization Cost Reduction Approach

In the area of distributed embedded systems, the literature includes a considerable number of works on synchronization tools or protocols but little ones on the non less important topic of synchronization cost. Synchronization operations impose temporal order on a software system by forcing some tasks to wait until other tasks complete their computations. However, synchronization costs can negatively affect embedded system performances. This paper proposes an effective approach for minimizing the synchronization cost by eliminating redundant synchronizations and describes tests performed under realistic conditions which have shown significant improvements.
