摘要

研究了无线传感器网络中支持硬实时通信的最优时隙分配方案(O-TDMA)。在关键任务系统中，提出了基于TDMA协议的O-TDMA方案和基于最坏情况可达利用率(WCAU)的实时性能分析方法。分析证明了O-TDMA方案比其他方案具有更好的性能。最后通过仿真算例验证了本文的结论。

Real-time Performance Analysis for Wireless Sensor Networks

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.
