Abstract :
In a wireless network environment, many studies have used multi-channel schemes to solve the single channel interference problem. Multi-channel can increase the network capacity. But it raises other problems, e.g., multi-channel hidden terminal problem and how to allocate channels to wireless nodes so that interference problem can be avoided and transmission performance can be significantly improved. Therefore, in this study, we proposed a scheme, called concentric-hexagon-oriented multi-channel assignment (CHOMA for short), in which APs are arranged as concentric-hexagon (C-hexa for short), and available channels are grouped and allocated to the C-hexa. We also schedule channels to reduce radio interference among APs, consequentially improving the transmission capability and performance of a wireless network.
