Capacity Estimation for IEEE 802.16 Wireless Multi-Hop Mesh Networks

For a given multi-hop route in an IEEE 802.16 mesh network, we are interested in finding its end-to-end capacity so that admission control can be performed. The end-to-end capacity is difficult to determine due to the interference between communicating nodes caused by the broadcast nature of radio propagation. In this paper, we first propose a method to determine link capacity between two nodes, after which a zone-based method is used to obtain the end-to-end capacity of a route. We demonstrate the effectiveness of the link capacity and end-to-end capacity computing methods through simulations.
