US 7,889,713 B2 · Transmission of management messages for relay networks

Abstract

Various example embodiments are disclosed relating to sending and processing messages in relay networks. In an example embodiment, a first unicast message indicating a plurality of wireless nodes included in a communication path between a base station and a path endpoint node in a wireless network may be received at a first receiving node, wherein the first unicast message may be received from a sending wireless node located neighboring to the first receiving node in the communication path. The first unicast message may be processed at the first receiving node. A second message may be sent based on a success/failure status of the processing from the first receiving node to a second receiving node included in the communication path.

Dependent claims

A method comprising:

receiving, at a first receiving relay station, a first unicast message including an identification of a specific communication path indicating an ordering of a plurality of intermediate wireless nodes between a base station and a path endpoint node in a wireless network, wherein the first unicast message is received from a sending wireless node located neighboring to the first receiving relay station in the communication path;
processing the first unicast message at the first receiving relay station;
sending, from the first receiving relay station to a second receiving relay station included in the communication path, a second message based on a success/failure status of the processing;
recording the communication path at the first receiving relay station;
and
routing subsequent traffic at the first receiving relay station based on the pre-recorded identified communication path.
