Wireless networked control systems (WNCSs) are widely used in many applications. A key challenge in WNCSs is to develop efficient data link layer (DLL) scheduling algorithms to achieve reliable end-to-end real-time communication. Previous research typically assumes that the network communication schedule of WNCS, once constructed and distributed, stays unchanged, thus cannot handle dynamic variations...
For real time task sets, allowing preemption is often considered to be important to ensure the schedulability, as it allows high-priority tasks to be allocated to the processor nearly immediately. However, preemptive scheduling also introduces some additional overhead and may not be allowed for some hardware components, which motivates the needs of non-preemptive or limited-preemptive scheduling....
