A Study on the Optimal Number of Interfaces in Wireless Mesh Network

In this paper, the authors obtain the optimal number of interfaces/channels in wireless mesh networks by simulation. The simulation study is done in static multi-channel multi-interface environment. When many nodes use a single interface/channel, collisions of RTS/CTS result in network performance degradation. To avoid such degradation and reduce interference among adjacent nodes, use of multi-interface/channel is considered. 802.11a and 802.11b offer 12 and 3 orthogonal channels and multi-interface/channel scheme could be applied. But rare research about the optimal number of interfaces/channels has been studied. In this paper, simulation study for the optimal number of interfaces/channels in wireless mesh network is performed.
