A fundamental study on routing and scheduling for multi-hop wireless networks with adaptive array

The interference between nearby links in a wireless multi-hop network degrades the area spectral efficiency. Thus there have been many works on a use of narrow beam antenna or adaptive array capable of forming nulls. Especially, the adaptive array allows simultaneous transmissions in multiple links within a limited area by suppressing the interference among those. However, efficient routing and scheduling are definitely required to exploit the benefit. In the paper, the performance on achievable system throughput is evaluated under ideal routing and scheduling. The results successfully indicate the potential ability of the adaptive array.
