Abstract

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.

Claims

1. In the operation of an ad hoc wireless network utilizing a data communication device as a node of the network, wherein the data communication device includes a two-way communications component and a wake-up transceiver that receives a wake-up broadcast while the two-way communications component remains in a dormant state, a method comprising:

transmitting the wake-up broadcast comprising a data construct to one or more additional nodes of the network, wherein the data construct comprises;

a wake-up identifier of the data communication device;

a node identification; and

an encryption key,

wherein the encryption key is configured to encrypt at least the wake-up identifier and the node identification.

2. The method of claim 1, wherein the encryption key follows the wake-up identifier and the node identification in the data construct.

3. The method of claim 2, wherein the data construct comprises 40 bits, wherein a first 32 bits of the data construct include the wake-up identifier and the node identification, and wherein a last 8 bits of the data construct include the encryption key.

4. The method of claim 1, wherein the encryption key is a symmetric encryption key.

5. The method of claim 1, wherein the encryption key is an asymmetric encryption key.

6. The method of claim 1, wherein the data construct further comprises a transmission count regarding wake-up broadcasts transmitted by a node.

7. The method of claim 1, wherein the data construct further comprises application specific data.

8. The method of claim 1, wherein the data construct further comprises an indication of the status of a sensor.

9. The method of claim 1, wherein the data communication device is a node in a common designation wireless ad hoc sensor network.

10. The method of claim 1, wherein the data communication device is a node in a class based wireless ad hoc network.

11. A data communication device as a node of an ad hoc wireless network, the data communication device comprising:

a two-way communications component;

a wake-up transceiver, wherein the transceiver receives a wake-up broadcast while the two-way communications component remains in a dormant state;

a memory; and

a processor coupled to the memory, wherein the processor is configured to execute instructions to;

transmit the wake-up broadcast comprising a data construct to one or more additional nodes of the network, wherein the data construct comprises;

a wake-up identifier of the data communication device;

a node identification; and

an encryption key,

wherein the encryption key is configured to encrypt at least the wake-up identifier and the node identification.

12. The device of claim 11, wherein the encryption key follows the wake-up identifier and the node identification in the data construct.

13. The device of claim 12, wherein the data construct comprises 40 bits, wherein a first 32 bits of the data construct include the wake-up identifier and the node identification, and wherein a last 8 bits of the data construct include the encryption key.

21. A data communication device as a node of an ad hoc wireless network, the data communication device comprising:

a two-way communications component;

a wake-up transceiver, wherein the wake-up transceiver receives a wake-up broadcast while the two-way communications component remains in a dormant state;

a processor; and

a non-transitory processor readable medium, coupled to the processor, including instructions to;

transmit the wake-up broadcast comprising a data construct to one or more additional nodes of the network, wherein the data construct comprises;

a wake-up identifier of the data communication device;

a node identification; and

an encryption key,

wherein the encryption key is configured to encrypt at least the wake-up identifier and the node identification.
