A Banyan-Tree Topology for Railway Wireless Mesh Network

In this paper, we propose a banyan-tree topology for the railway wireless mesh network (WMN), which could normally stretch up to hundreds and thousands kilometer along the railway. Theoretical analysis and numerical studies show that the proposed banyan-tree topology is appropriate for the implementation of multi-hop WMN along the railway with improved network robust, and is feasible to deploy because it requires fewer portals to the wired network.
