Claim Text:
1. A method for a lighting node within a lighting infrastructure to communicate data to other nodes within a lighting sensory network, comprising: receiving, at the lighting node, a first message from a server, instructing the lighting node to enter into a sensor transmit mode associated with a first type of sensor data, the first message including transmission parameters which includes an encryption key for transmitting secure sensor messages associated with the first type of sensor data to the other nodes and a retransmit base interval associated with the first type of sensor data; storing the transmission parameters for use by the lighting node; obtaining, at the lighting node, the first type of sensor data; recording a timestamp associated with a time the first type of sensor data was obtained; storing, at the lighting node, the obtained first type of sensor data and the recorded timestamp; generating, by the lighting node, an encrypted sensor message using the encryption key, the encrypted sensor message including the obtained first type of sensor data and the recorded timestamp; and transmitting, by the lighting node, the encrypted sensor message by broadcasting the encrypted sensor message to the other nodes which are configured to operate in a listening mode, at least some of the other nodes representing authorized listening nodes configured to decrypt the encrypted sensor message with a decryption key provided by the server to the authorized listening nodes that corresponds to the encryption key.
