Abstract :
In this paper, an optimal time slot allocation scheme (O-TDMA) supporting hard real-time communication in wireless sensor networks (WSNs) is studied. In mission-critical system, O-TDMA scheme based on TDMA protocol and a real-time performance analysis method based on WCAU (the worst case achievable utilization) are proposed. Analytical proof that O-TDMA has better performance than other schemes is given. Finally simulative examples are presented to promote the conclusion.
