Traffic management employing interference management messages
First Claim
Patent Images
1. A method of multi-hop wireless communication, comprising:
- receiving, at a first wireless node, information relating to whether a second wireless node has data to be transmitted to the first wireless node;
determining whether quality of service associated with received data at the first wireless node is unacceptable;
determining, based on the received information, whether the unacceptable quality of service is a result of a traffic bottleneck affecting reception at the second wireless node; and
determining, based on the determination of whether the unacceptable quality of service is a result of a traffic bottleneck, whether to transmit an interference management message to limit transmissions by at least one wireless node that receives the message.

Abstract
Various traffic management techniques may be employed in a multi-hop wireless communication system. For example, a decision to transmit data to another node may be based on whether that node is able to effectively transmit its data. A decision to transmit an interference management message may be based on the amount of data a parent node may transmit. A decision to transmit an interference management message may be based on how effectively data is being transmitted. A weight may be assigned for an interference management message based on a traffic scheduling policy.
