Abstract: In one embodiment, a rendezvous request message is generated (e.g., by a sender) that specifies a channel C and a rendezvous time T for which a distributed message is to be transmitted in a frequency-hopping computer network. The rendezvous request message is then transmitted on one or more channels used in the computer network based on reaching a plurality of intended recipients of the distributed message with the rendezvous request message prior to rendezvous time T. Accordingly, the distributed message is then transmitted on channel C at rendezvous time T. In another embodiment, a device receives a rendezvous request message, and in response to determining to honor the rendezvous request message, listens for the distributed message on channel C at rendezvous time T.

Abstract: In one embodiment, a battery-operated communication device “quick-samples” a frequency hopping sequence at a periodic rate corresponding to a substantially low duty cycle, and is discovered by (e.g., attached to) a main-powered communication device. During a scheduled sample, the main-powered communication device transmits a control packet to be received by the battery-operated communication device, the control packet containing timing information and transmitted to account for worst-case clock drift error between the two devices. The battery-operated communication device responds to the control packet with a link-layer acknowledgment containing timing information from the battery-operated communication device. Accordingly, the two devices may re-synchronize their timing based on the timing information in the control packet and acknowledgment, respectively.
Abstract translation: 在一个实施例中，电池供电的通信设备以对应于基本上较低占空比的周期性速率“跳频”跳频序列，并且通过（例如附接到）主供电通信设备来发现。 在预定采样期间，主供电通信设备发送由电池供电的通信设备接收的控制分组，该控制分组包含定时信息，并且被传送以考虑两个设备之间的最坏情况时钟漂移误差。 电池供电的通信设备用包含来自电池供电通信设备的定时信息的链路层确认来响应控制分组。 因此，两个设备可以分别基于控制分组和确认中的定时信息重新同步其定时。
