Abstract:
1. A computer implemented method comprising: identifying data to be included in a data packet; determining that an amount of the data collected exceeds a threshold; in response to determining that an amount of the data collected exceeds the threshold, generating one or more chirp packets associated with the data packet, wherein the chirp packet includes a chirp interval and the chirp packet is sent throughout the course of a sleep period of a device; initializing, for each chirp packet, an offset variable to zero subtracted from the sleep period; broadcasting the one or more chirp packets including data indicating a delay before transmitting the data packet; adjusting, for each chirp packet, the offset variable until the offset time variable reaches or exceeds the chirp period; determining that the adjusted offset variable satisfies a threshold; and in response to determining that the adjusted offset variable satisfies the threshold, transmitting the data packet.
