A Mesh×Chain Graph Model for MIMO Scheduling in IEEE802.16 WMN

This paper supposes a new graph model for wireless Mesh Networks (WMN) with MIMO channels. The model is based on the anttena model and single channel mesh, place edges into different channel plane avoiding interference. The active edge group algorithm select the most active edges without interference, then perform high throughput. The coding scheme in the hexagonal graph keeps the symmetry, and can easily use translate transformation for other receiver routing requirements. Layered active edge group scheduling and star routing schemes are proposed. We show the relation between node coding and hop number in a proposition.
