Abstract
A mechanism for end-to-end link quality indication, including a wireless router, coupled to other wireless routers over a multi-hop mesh network, responsive to a first message received from an origination device, configured to forward the first message to a next one of the other wireless routers in route to a destination device. The wireless router has received signal strength indication (RSSI) logic, that adds first RSSI information to a first field of the first message, and that adds second RSSI information to a second field of an acknowledgement message prior to transmitting the acknowledgement message to the origination device. The first and second RSSI information, along with intermediate RSSI information added by one or more of the other wireless routers along a path from the origination device to the destination device, is aggregated into a single term representative of total round-trip quality for the first message and the acknowledgment message.
