Abstract: A node in network is configured to buffer data received from other nodes across multiple channels. The node process a portion of the buffered data associated with a subset of those channels. When the node receives data on that subset of channels that includes a notification, the node then processes a larger portion of the buffered data associated with a larger number of channels. In doing so, the node may identify additional notifications include within data that was buffered but not previously processed. The node may also coordinate with other nodes in order to process buffered data upon identification of a notification.
