摘要
Since the duty cycle of S-MAC is fixed and longer, it will cause longer idle time and latency of data packets under light loads. To solve these problems we present a new MAC protocol in which the sleep/wakeup schedules of the sensor nodes are adaptively determined, sensor nodes may sleep frequently. And also it minimizes control-packet overhead. Simulation shows that the new MAC is of significant effective in lessening delay time and power saving.
