US 9,001,870 B2 · T/R first and second intervals for strobes and data packets

Abstract

The duration of receiver on-times may be minimized by sensing and reacting to communication channel power levels at intervals. When no energy is detected on the communication channel, then the receiver may be turned off for a channel sampling interval. If energy is detected on the channel, then the receiver may remain on to determine if a received message is associated with the device. Receiver on-time may also be minimized by adjusting the timing of messages used for broadcast messages sent by routing or other protocols. Broadcast messages, such as network routing topology messages, may be controlled in two phases. In a first phase, the broadcast messages are sent with at a high rate to allow nodes to join the network rapidly. In a second phase, the broadcast messages are sent with at a lower rate to minimize interference with data and other messages in the network.
