无线传感器系统中的调度传输
Scheduled transmission in a wireless sensor system
US-7339957-B2用于无线传感器网络的节能调度传输方法。
专利摘要
一种用于提供环境监测和控制的方法，包括提供无线节点网络，无线节点包括传感器节点阵列和致动器节点阵列，每个无线节点包括无线收发器、处理器以及传感器装置或致动器装置之一。在一个实施例中，接收方无线节点通过从接收方无线节点向发送方无线节点发送包括下一调度传输时隙的确认消息来调度下一传输的时隙。无线节点被关闭，直到下一调度时隙，此时无线节点同步开启。在另一实施例中，发送方无线节点通过发送包括下一调度传输时隙的消息来调度下一传输，并且接收方无线节点发送确认所选时隙的确认消息。
Original abstractA method for providing environmental monitoring and control includes providing a network of wireless nodes, the wireless nodes includes an array of sensor nodes and an array of actuator nodes, each wireless node including a wireless transceiver, a processor and one of a sensor device or an actuator device. In one embodiment, the receiver wireless node schedules the time slot for the next transmission by sending an acknowledgement message from the receiver wireless node to the sender wireless node including a time slot for the next scheduled transmission. The wireless nodes are turned off until the next scheduled time slot when the wireless nodes are turned on synchronously. In another embodiment, the sender wireless node schedules the next transmission by sending a message including a time slot for the next scheduled transmission and the receiver wireless node sends an acknowledgement message acknowledging the selected time slot.
