Wake-up broadcast including network information in common designation ad hoc wireless networking

摘要

A data communication device includes both a two-way communications component having a first receiver and transmitter, and a second receiver. The second receiver activates the two-way communications component from a dormant state upon receipt by the second receiver of a wake-up broadcast that includes a wake-up identifier of the data communication device. A method of providing information via the second receiver—which information is auxiliary to the wake-up of the two-way communications component—includes transmitting a wake-up broadcast capable of being received by the second receiver. The wake-up broadcast includes a data construct including a wake-up identifier and the auxiliary information. The wake-up identifier may or may not be a wake-up identifier of the data communication device. Nevertheless, the auxiliary information is received and recorded by the data communication device via the second receiver with the two-way communications component remaining in the dormant state.

主权项

1. In the operation of an ad hoc wireless network utilizing a data communication device as a node of the network, the data communication device including both,
a two-way communications component comprising a first receiver and transmitter, and a second receiver,wherein the second receiver activates the two-way communications component from a dormant state upon receipt by the second receiver of a wake-up broadcast that includes a wake-up identifier of the data communication device,
a method of providing information via the second receiver, which information is auxiliary to the wake-up of the two-way communications component, the method comprising:
(a) receiving, via the second receiver of the data communications device, a wake-up broadcast including a data construct comprising a wake-up identifier and the auxiliary information; and(b) determining, at the data communication device, that the wake-up identifier of the received wake-up broadcast does not correspond to the wake-up identifier of the data communication device and, thereby, not activating the two-way communications component from the dormant state based upon the received wake-up broadcast,
(i) processing, at the data communication device irrespective of whether the wake-up identifier of the received wake-up broadcast corresponds to the wake-up identifier of the data communication device and irrespective of whether the two-way communications component is in the dormant state, the received auxiliary information to ascertain networking information; and(ii) storing, at the data communication device, data representing the ascertained networking information;(iii) wherein the auxiliary information comprises a node identification from which the wake-up broadcast is transmitted;(iv) wherein the ascertained networking information includes the confirmed presence of another node of the network within a single hop from the data communication device, such information being ascertained based on the node identification from which the wake-up broadcast was transmitted; and(v) wherein the ascertained networking information includes the presumed presence of a node corresponding to the wake-up identifier of the received wake-up broadcast.
