Abstract

In embodiments of the present invention improved capabilities are described for associating a first node in a mesh network with an electrical device, wherein the electrical device comprises a home control device, enabling the mesh network to perform channel adjustment, transmitting data through the mesh network between the first node and a second node in the mesh network, wherein the transmission utilizes channel adjustment; and performing an action based at least in part on the transmitted data.

Claims (26)

1. A method, comprising:

tuning a wireless receiver to a channel;

at the wireless receiver, receiving a preamble on the channel;

determining that the preamble contains more than a threshold number of symbols;

at the wireless receiver, receiving a message on the channel; and

upon receipt of the message, retuning the wireless receiver to another channel.

2. The method of claim 1 , further comprising:

transmitting, to an intended recipient, a concatenation of a second preamble and a second message;

determining that an intended recipient of the second message failed to receive the second message;

determining a change to a topology of a wireless mesh network; and

in view of the change to the topology, retransmitting the second message to a different intended recipient.

3. The method of claim 2 , wherein determining the change comprises:

requesting a network topology update from a computer other than the intended recipient.

4. The method of claim 2 , wherein determining the change comprises:

broadcasting an explore frame into the wireless mesh network.

5. The method of claim 2 , wherein determining the change comprises:

receiving a broadcast from a computer other than the intended recipient, the broadcast including network topology update.

6. The method of claim 2 , wherein determining that an intended recipient failed to receive the second message comprises:

during a time interval, failing to detect transmission of the message by a node other than the intended recipient; and

retransmitting the concatenation after expiration of the time interval.

7. The method of claim 6 , wherein determining that the intended recipient failed to receive the second message further comprises:

during the time interval, failing to receive an acknowledgement frame from the intended recipient.

8. The method of claim 1 , further comprising:

powering up the wireless receiver prior to tuning it to the channel;

retransmitting the message; and

powering down the wireless receiver upon retransmitting the message.
