Node repair in a mesh network
First Claim
1. A method comprising:
- sensing an error in a network topology based on a network transmission failure;
identifying a failed node in the network;
in response to sensing the error, flooding accessible mesh network routes from a first node to a destination node with transmissions of explore frames originating at the first node, wherein each transmitted explore frame is adapted to collect node identifiers of each intermediate node that is traveled en route to the destination node, and to instruct the destination node to transmit a report frame back to the first node once each transmitted explore frame reaches the destination node;
receiving the report frame at the first node from the destination node, wherein the report frame includes all node identifiers associated with the transmission of the explore frame from the first node to the destination node;
determining at least one functional network route from the first node to the destination node based at least in part on the node identifiers received in association the report frame, wherein the node identifiers indicate a functional node path from the first node to the destination node comprising nodes which support a faster transmission speed of the at least one functional network route from the first node to the destination node; and
transmitting an instruction to the destination node from the first node based on the functional node path.

Abstract
In embodiments of the present invention improved capabilities are described for sensing a change in a network topology using a discovery node in a mesh network; transmitting an explore frame, based at least in part on the sensed change, from the discovery node to a destination node using an intermediate node; receiving a response to the explore frame from the destination node; determining at least one functional network route from the discovery node to the destination node based at least in part on route information received in association with the response to the explore frame, wherein the route information includes a node path; and transmitting an instruction to the destination node from the discovery node based on a reverse node path.
