Event Triggering Mechanism on a Time Base: A Novel Approach for Sporadic as well as Periodic Task Scheduling
A novel concept involving the combination of the two individual time triggered and event triggered methodologies is presented aiming in gaining the benefits of the respective mechanisms and attaining high system level performance. The major advantage of the work presented is the best utilization of the system resources available with gained flexibility. A detailed explanation of the proposed approach is presented. Simulation studies were conducted for the approach validation.
