ABSTRACT:
A packet forwarding technique is presented that forwards data packets through a multi-hop wireless network employing multi-radio nodes. In each multi-radio node, an output buffer is shared among the radios. Outgoing packets are stored in this buffer. Whenever there is a transmission opportunity on the radios sharing the output buffer, the node examines the buffer and searches for packets that are scheduled to be transmitted to a neighboring node having an open communication link with the transmitting node. The packet in the discovered group that has the highest transmission priority is then transmitted to its next scheduled node.
