Abstract :
In this paper we investigate the performance of reconflgurable antennas in an MIMO ad-hoc network. The nodes employ the multiuser waterfllling (known also as iterative waterfllling) power allocation [1], [2] method and we use network sum capacity as a performance metric. We study a centralized configuration selection scheme, which can be used as an upper bound in the sum capacity using reconflgurable antennas, as well as a simple distributed configuration selection scheme, suitable for use in an ad-hoc MIMO network.
