- Abstract
- A mission-critical application model under asymmetric, unreliable wireless links is established for cyber physical systems. Based on reliability-guaranteed mechanism, deadline-guaranteed mechanism and online slack reclaiming mechanism, a low energy-consumption messages scheduling algorithm under reliability and real-time constraints is proposed and proved to be a low time complexity approach. The proposed algorithm can transmit messages with minimal energy without violating their dependable requirements. Simulations show the superiority and effectiveness of the proposed algorithm on energysaving and reliability-improving.
