A data-rate adaptive hidden-terminal problem immune MAC protocol for multi-channel wireless mesh networks

Multi-channel wireless mesh network (WMN) is highlighted in WMNs because of its high data rate and low access delay. Since WMN is distributed, self-organized and mobile, designing the medium access control (MAC) protocol for multi-channel WMN is a big challenge. In this paper, we proposed a MAC protocol for multi-channel WMN. In our scheme, the number of channels can be adjusted freely according to the needs of WMN. Moreover, the data rate of our scheme is adaptive and the hidden terminal interference can be avoided. Theoretical analyses and performance evaluations show that our scheme outperforms the proposed common control channel (CCC) in terms of the high throughput and low access delay.
