| Research Abstract |
In the wireless mesh network with nodes capable beam-forming, we have obtained the following three major achievements. (1) The approximate solution for maximizing sum-capacity has been developed and its high performance has been shown in network-coded links. (2) An suboptimum routing has been proposed for a wireless mesh network with nodes capable beam-forming and its high throughput performance has been indicated. (3) We have derived an approximated solution for the optimum beam-forming at the source node in a two-step relay.
