Abstract: A method controls a wireless network, which includes a controller and a plurality of network elements. The method includes determining interference in the wireless network using radio-link measurements, generating an interference matrix identifying the interference in the wireless network, and generating an adjacency matrix based on the interference matrix identifying locations having unacceptable levels of interference in the wireless network. The method also includes allocating channels and corresponding transmission powers in the wireless network to reduce the unacceptable levels of interference. The method is performed at predetermined fixed time intervals and when a new network element is added to the wireless network.

Abstract: A method is provided for managing performance of a wireless network by a server. The method includes generating performance data of the wireless network by having a plurality of network elements communicate with each other to determine signal attenuation among each pair of the plurality of network elements. The method also includes determining interference within the wireless network interference based on generated performance data, and generating an interference matrix identifying the interference in the wireless network. The method further includes generating an adjacency matrix, based on the interference matrix, identifying locations having unacceptable levels of interference in the wireless network, and allocating channel frequencies and corresponding transmission powers in the wireless network based on the adjacency matrix, in order to maximize an aggregate throughput of the wireless network.
