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.

Claims (10)

1. A system for enabling roaming comprising: a cloud environment comprising distributed memory and computational facilities; a first gateway providing access to the cloud environment; a second gateway providing access to the cloud environment; and at least one mobile sensor node, configured to communicate with the cloud environment through either of the first and second gateways, the gateway for communication at any time being selected based on the location of the mobile sensor node at that time, and wherein 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.
2. The system in accordance with claim 1, wherein the encrypted connection is also used for authentication.
3. The system in accordance with claim 1, wherein the cessation of communication through one of the first and second gateways and initiation of communication through the other of the first and second gateways is caused by radio disturbance on the established channel or by the gateway loosing connection or power, or by the gateway being removed.
4. The system in accordance with claim 1, wherein the encrypted connection is a secure link.
5. The system in accordance with claim 1, wherein for a message going from the sensor node to the cloud, the gateway in use forwards the message to the cloud with engaging in encryption or decryption.
6. The system in accordance with claim 5, wherein the gateway tests the message for errors.
7. The system in accordance with claim 1, wherein the cloud is configured to detect recipt of multiple copies of the same message from multiple gateways.
8. The system in accordance with claim 5, wherein the cloud is configured to decrypt the message and verify of authenticity.
9. The system in accordance with claim 1, wherein for messages going from the cloud to a sensor node the cloud is configured to select one gateway as a contact point for the sensor node.
10. The system in accordance with claim 1, wherein the selection of a gateway is based at least in part on which gateway has the best radio communication link with the sensor.
