Abstract
The performance of wireless network is significantly influenced by radio signal co-channel interference. In this paper, we address the issue of configuring a given set of wireless nodes so that co-channel interference within this network is minimized. The issue of interference is very important, especially in the case where a wireless node may have multiple network interference cards, and each of these interface can operate on difference channels. We divide the
task into two stages topology control and interference
control. The topology configuration is to establish a set of links so that the resulting topology will have a certain connectivity property. The channel assignment is to assign each wireless communication link a channel so that the interference within this network will be minimized. We present two algorithms that determine
the network topology and channel assignment pattern respectively. Experiment results shows that our scheme deliver better performance than the previous works in terms of interference and communication throughput.
