摘要
针对无线传感器网络的特点,提出低能耗低延时的无线传感器网络MAC协议——CRMAC。该协议将节点工作时间分离为信道预约时间和数据发送时间。在信道预约时间里,有数据发送的节点发送预定信道帧通知多跳的转发节点,确定节点的数据发送时间框架。在数据传送时间里,只有需要发送或接收数据的节点被唤醒,而其它节点保持睡眠状态。
Taking account of the demand of wireless sensor networks (WSN),the article provides a energy-efficient and low-latency MAC protocol:CRMAC (channel reservation mac protocol).This protocol divides the time of working into channel reservation time and data transmission time.In reservation time,the node which need send data notifies others and make a data transmission schedule.in data transmission time, only scheduled nodes are awake and others remain sleeping.
