Routing tree construction in WiMAX mesh networks

In the paper we investigate the methods of constructing the routing tree in WiMAX networks with mesh topology. The concept of network efficiency optimization by building the routing tree characterized by selected topological properties that are independent on network load is presented. As an important partial result, correlations between topological parameters of the tree and network efficiency have been estimated. The parameters exhibiting the strongest correlations allow creation of well performing routing trees by optimizing the tree topology only. In order to estimate the network performance under load a fast, modular WiMAX network simulator has been created.
