  • Methods and systems for data consistent search and storage using trees
    Patent number: 11962494
    Abstract: Two versions of a database can be held in two trees that have many of the same nodes. Both trees can be concurrently searched using recursive algorithms. A root node indicator indicates a root node for a tree search algorithm. The root node indicator can indicate a first root node of a first tree. A tree search algorithm can identify a record node in the first tree. Intermediate nodes between the record node and the first root node can be identified and retained nodes can be identified. A second root node and replacement intermediate nodes can be instantiated. A second tree that includes the second root node, the replacement intermediate node, and the retained nodes can be created. The root node indicator can be set to indicate the second root node after creating the second tree.

  • Fault tolerance in a wireless network
    Patent number: 7715308
    Abstract: A wireless network comprises a plurality of nodes that communicate over wireless communication links. A virtual site is established at a primary node included in the plurality of nodes. A backup node is selected for the virtual site from the plurality of nodes. When the primary node is able to do so, the primary node performs predetermined processing for the virtual site and replicates at the backup node data related to the processing. When the primary node is unable to perform the processing, the backup node performs the processing for the virtual site using at least some of the data replicated at the backup node.
