Abstract:
A system includes multiple nodes, where each node includes one or more 802.11 wireless radios. The nodes are arranged in a hierarchical tree structure in which one or more nodes residing in one level of the tree structure are configured to communicate with one or more nodes residing in another level of the tree structure to propagate information in the tree structure. At least a first of the nodes is configured to operate its associated radio(s) in an 802.11 access point mode and in an 802.11 station mode. The first node is configured to relay data to and from one or more nodes in a lower level of the tree structure using the 802.11 access point mode. The first node is further configured to transmit data to and receive data from one or more nodes in a higher level of the tree structure using the 802.11 station mode.
