Abstract
A wireless network with a star topology includes a first central node, a second central node, wherein the first and second nodes are functionally equivalent. A set of leaf nodes are configured to communicate with either the first central node or the second central node via wireless links, depending whether the central nodes are active or inactive.
Claims20
A wireless network with a star topology, comprising:
- a first central node;
- a second central node, wherein the first and second nodes are functionally equivalent;
- a set of leaf nodes configured to communicate with either the first central node or the second central node via wireless links, depending whether the central nodes are in active mode or standby mode.
A method for operating a wireless network with a star topology, comprising:
- communicating between a first central node and a set of leaf nodes when the central node is in an active mode;
- detecting a failure in the communicating;
- activating a second central node functionally equivalent to the first second node in response to the detecting of the failure, and deactivating the first central node;
- and
- communicating between the second central node and the set of the leaf nodes after the activating and the deactivating.
