Inter-channel interference cancellation in wireless mesh network
Wadhah Al-Mandhari, Nobuo Nakajima · 2009
Abstract:- Interference is one of the challenges that limit the performance of Wireless Mesh Networks (WMN). It became a major issue with new devises being equipped with more than one radio interface. This research emphasizes on impact of interference in multi-hop / multi-radio WMN’s throughput as a result of utilizing dual radios in WMN’s station. Various laboratory experiments in this research indicates that the IEEE802.11 non-interfering channels for the 2.4GHz band still exhibit some level of interference. Furthermore, we proposed an interference cancellation circuit that showed a noticeable throughput enhancement in our experiments. This validates the proposed solution for interference suppression and throughput enhancement..
