Title: SENSOR ROAMING AND LINK HANDOVER
Abstract:
Systems and methods for enabling roaming include a cloud environment comprising distributed memory and computational facilities as well as multiple gateways providing access to the cloud environment. A mobile sensor node is configured to communicate with the cloud environment through one of the gateways. The gateway may be selected based on the location of the mobile sensor node at that time. The mobile sensor node and cloud are configured to establish an encrypted connection that is independent of the gateway being used to transfer data over the encrypted the connection, such that when the mobile sensor node ceases communication through one of the first and second gateways and initiates communication through the other of the first and second gateways, the encrypted connection is maintained without the need for a new link bring-up.
