Abstract

A wireless network software access point (AP) integrated into a wireless device allows a wireless network to be configured automatically and dynamically maintained with minimal user intervention. Such automatic configuration includes: whether to configure the Soft AP enabled device to be an AP Node or a Station Node; specifics of wireless radio link configuration, routing or bridging relationships with other networking devices attached to the host-computing device; and firewall configuration. Such automatic configurations are based on the automatic detection of the network environment attached to the Soft AP enabled device. The automatic configurations may also be based on the intelligent interactions among different Soft AP enabled devices in the wireless network, which often includes devices with and without Soft AP functionalities.

Claims

1. A method for dynamically configuring a wireless network comprising the steps of

testing a first wireless node against a predetermined criteria,

establishing the first node as an access point if the predetermined criteria is satisfied and establishing a link with a second node, and

establishing the first node as a station node if the predetermined criteria is not met and an association can be made with an access point.

2. The method of claim 1, further including the step of

establishing the first node as an access point if the predetermined criteria is not met and no association can be made with an access point after a predetermined period of time.

3. The method of claim 1, further including the step of periodically retesting at least some nodes of the network to permit reconfiguration of the nodes as either access points or station nodes in accordance with the predetermined criteria.

4. A method of dynamically configuring a wireless network including the steps of

establishing the network among a plurality of nodes by establishing at least one of the nodes as an access point and at least one other node as a station node,

optimizing the network by minimizing the number of access points while maintaining a wireless connection to each node within the network, and

extending the network by connecting to newly added nodes, including reconfiguring an existing station node as an access point if required to establish communication with the newly added node.

5. The method of claim 4 further including the step of comparing a node against a predetermined criteria to determine if the node is an edge node.

6. The method of claim 4 further including the step of testing a node against a predetermined criteria to determine whether to configure that node as an access point or a station node.

7. The method of claim 6 further including the step of periodically verifying whether the predetermined criteria is still met.

8. The method of claim 7 further including the step of reconfiguring the node in accordance with whether the predetermined criteria is still met.

9. The method of claim 6 further including associating a node with an access point within the network.

10. The method of claim 9 further including testing the association of a node with a plurality of access points to determine whether to associate with at least one of the access points.

11. The method of claim 10 further including the step of configuring a node as an access point if the results of the testing result in no association being made with a pre-existing access point.

12. A dynamically reconfigurable network comprising

a plurality of nodes, at least some of the nodes being capable of being configured as either an access point or a station node,

a computer program resident within at least some of the nodes for testing whether to establish a given node as an access point or a station node, and

a timer for causing at least one node to rerun the computer program.

13. The network of claim 12 wherein at least some of the nodes are not reconfigurable.

14. The network of claim 12 wherein the computer program includes a predetermined criteria against which performance of a node within its environment is tested to determine whether to configure that node as an access point or a station node.
