摘　　要：研究无线传感器网络TinyOS的体系结构、通信机制及内核调度机制.针对TinyOS调度机制的不足,提出一种改进的调度策略——基于时限的轮转调度策略.在由micaZ节点搭建的实验平台上对改进机制进行实验,实验结果表明,基于时限的轮转调度策略提高了无线传感器网络通信的吞吐量,改善了无线传感器网络的通信性能.Research on the architecture, communication mechanism and Schedule mechanism of TinyOS in Wireless Sensor Networks. According to the shortages of Scheduler, an improved round- robin scheduling strategy based on deadline is proposed, and it is validated on the micaZ platform. The result of simulation demonstrates that the improved schedule strategy can increase the throughput of communication and improve the communication performance.
