Efficient Channel Assignment Algorithms for Infrastructure WLANs Under Dense Deployment
It is well known that WLAN based on the IEEE 802.11 standard suffers from interference and scalability problems due to a limited number of non-overlapping channels. In order to mitigate the interference problem, channel assignment algorithms have been a popular research topic in recent years. It has been shown that such algorithms can greatly reduce the interference among wireless access points. However, in this paper, the authors show that previously proposed channel assignment algorithms may lead to an increased number of hidden nodes in dense network deployments.
