Title: Establishing a multi-hop route in wireless network
Inventor: ZHONG FAN
IPC: H04L12/28
Filed: 2007-12-21
Abstract: A transmitter initiates multi-hop route discovery when a direct link between a source transmitter and a destination receiver is unavailable. The transmitter initially transmits RREQs to candidate nodes that are identified as being in substantially the same direction as the destination node. The transmitter, and also any intermediate nodes that route the RREQ, may delete, insert and/or modify channel quality information from and in the RREQ. The channel quality information may be derived from signal quality measurements monitored over time. In this way, a receiver may select one of the multi-hop routes based on signal quality.
