In one example, a method is provided for a lighting node within a lighting infrastructure to communicate data to other nodes within a lighting sensory network. The method includes 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 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. The method includes obtaining, at the lighting node, the first type of sensor data and recording a timestamp associated with a time the first type of sensor data was obtained. The lighting node generates an encrypted sensor message including the obtained first type of sensor data and the recorded timestamp; and transmits the encrypted sensor message by broadcasting the encrypted sensor message to at least one other operating in an authorized listening mode.

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 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 an encryption key provided by the server, the encrypted sensor message including the obtained first type of sensor data and the recorded timestamp; andtransmitting, by the lighting node; the encrypted sensor message by broadcasting the encrypted sensor message to at least one node among the other nodes, the at least one node configured to decrypt, using a decryption key provided by the server and corresponding to the encryption key, the encrypted sensor message. 2. The method of claim 1, wherein the transmission parameters provided by the server to the lighting node include the encryption key, and the encryption and decryption keys represent symmetric keys generated using cryptography symmetric-key algorithms. 3. The method of claim 1, wherein the generated encrypted sensor message further includes one or more of nonce data, version data, sensor identifier data, debugging identifier data, the sensor data, and position data related to the lighting node. 4. The method of claim 1, wherein transmitting, by the lighting node, the encrypted sensor message by broadcasting the encrypted sensor message to at least one node among the other nodes further comprises broadcasting the encrypted sensor message to the at least one node among the other nodes with user datagram protocol (UDP) packets. 5. The method of claim 1, wherein the lighting sensory network is a wireless network from a group of wireless network types that includes at least an ad hoc wireless network. 6. The method of claim 1, further comprising determining, by the lighting node, whether to retransmit the generated encrypted sensor message based on at least one of a predefined age threshold and a number of previous transmissions of the generated sensor message. 7. The method of claim 6, further comprising discarding, by the lighting node, the generated sensor message in response to determining not to retransmit the generated encrypted sensor message based on at least one of the predefined age threshold and the number of previous transmissions of the generated sensor message. 8. A system, comprising: a lighting node within a lighting infrastructure to communicate data to other nodes within a lighting sensory network;processors; anda memory storing instructions that, when executed by at least one processor among the processors, cause the system to perform operations 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 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 an encryption key provided by the server, the encrypted sensor message including the obtained first type of sensor data and the recorded timestamp; andtransmitting, by the lighting node, the encrypted sensor message by broadcasting the encrypted sensor message to at least one node among the other nodes, the at least one node configured to decrypt, using a decryption key provided by the server and corresponding to the encryption key, the encrypted sensor message. 9. A non-transitory machine-readable medium storing instructions that, when read by a machine, cause the machine to perform operations within a lighting infrastructure enabling a lighting node to communicate data to other nodes within a lighting sensory network, the operations comprising, at least: 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 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 an encryption key provided by the server the encrypted sensor message including the obtained first type of sensor data and the recorded timestamp; andtransmitting, by the lighting node, the encrypted sensor message by broadcasting the encrypted sensor message to at least one node among the other nodes, the at least one node configured to decrypt, using a decryption key provided by the server and corresponding to the encryption key, the encrypted sensor message.
