Abstract

Embodiments of the invention include methods and systems for architectures for wireless avionics communication networks. The embodiments further include detecting a signal strength of wireless nodes, assigning a primary data controller and standby data controller for each of the wireless nodes based at least in part on the signal strength, and generating a deployment matrix based on the assignment of the primary data controller and the standby data controller. The embodiments also include broadcasting the deployment matrix over a wired connection, allocating a buffer size based on data rates of each of the wireless nodes connected to the primary data controller and the standby data controller, and exchanging data based on the deployment matrix.

First claim

What is claimed is:

1. A method for architectures for wireless avionics communication networks, comprising:
detecting a signal strength of wireless nodes;
assigning a primary data controller and standby data controller for each of the wireless nodes based at least in part on the signal strength;
connecting each of the wireless nodes to the primary data controller and the standby data controller;
generating a deployment matrix based on the assignment of the primary data controller and the standby data controller;
broadcasting the deployment matrix over a wired connection;
allocating a buffer size based on data rates of each of the wireless nodes connected to the primary data controller and the standby data controller; and
exchanging data based on the deployment matrix.

2. The method of claim 1 , wherein the deployment matrix identifies a primary channel and standby channel of the primary data controller and a primary channel and standby channel of the standby data controller.

3. The method of claim 1 , further comprises responsive to the failure of the primary channel of the primary data controller, selecting a secondary channel of the primary data controller indicated in the deployment matrix.

4. The method of claim 3 , further comprises responsive to a failure of the standby channel of the primary data controller, selecting a primary channel of a standby data controller indicated in the deployment matrix.

5. The method of claim 4 , further comprises responsive to a failure of the primary channel of the standby controller, selecting a standby channel of the standby controller indicated in the deployment matrix.

6. The method of claim 5 , further comprises responsive to a failure of the standby channel of the standby data controller, entering an idle mode.

7. The method of claim 1 , further comprises implementing a dynamic buffering scheme, wherein each buffer is configured to receive data at different data rates from each of the wireless nodes.

8. The method of claim 1 , wherein a network manager transmits data obtained from wireless nodes to an aircraft application for monitoring health of an aircraft.

9. A system for architectures for wireless avionics communication, comprising:
a network manager;
a primary data controller having a first and second communication interface;
a standby data controller having a first and second communication interface, wherein the primary data controller and the standby data controller are coupled to the network manager over a wired connection; and
one or more wireless nodes, wherein each of the one or more wireless nodes are configured to transmit data at different rates over a wireless connection, wherein each of the one or more wireless nodes are connected to the primary data controller and connected to the standby data controller.

10. The system of claim 9 , wherein the primary data controller and the standby data controller each include a dynamic buffer configured to receive data at different rates from the one or more wireless nodes.

11. The system of claim 9 , wherein the network manager stores a deployment matrix identifying a primary channel and standby channel of the primary data controller and a primary channel and standby channel of the standby data controller.

12. The system of claim 11 , further comprises responsive to the failure of the primary channel of the primary data controller, one or more wireless nodes communicate over a secondary channel of the primary data controller indicated in the deployment matrix.

13. The system of claim 12 , further comprises responsive to a failure of the secondary channel of the primary data controller, one or more wireless nodes communicate over a primary channel of a standby data controller indicated in the deployment matrix.

14. The system of claim 13 , further comprises responsive to a failure of the primary channel of the standby controller, one or more wireless nodes communicate over a standby channel of the standby controller indicated in the deployment matrix.

15. The system of claim 14 , further comprises responsive to a failure of the standby channel of the standby data controller, one or more wireless nodes enter an idle mode.
