US Patent 10033706 Secure offline data offload in a sensor network

Methods and systems for secure data offload in a sensor network. The method comprises offloading data indicative of sensor measurements from a wireless sensing device to a gateway device through a first secure communication channel; and storing the data at the gateway device if there is not currently a second secure communication channel established between the gateway device and the management server. The method continues with offloading the data to the management server when the second secure communication channel is established; and reconciling the data at the management server to generate reconciled sensor measurements in which duplicates have been removed.
