The IEEE 802.16 standard defines mesh mode as one of its two operational modes in Medium Access Control (MAC). In the mesh mode, peer-to-peer communication between Subscriber Stations (SSs) is allowed, and transmissions can be routed via other SSs across multiple hops. In such an IEEE 802.16 mesh network, accurate and reliable determination of dynamic link capacity and end-to-end capacity of a given multi-hop route is crucial for robust network control and management. The dynamic capacities are difficult to determine in a distributed system due to decentralized packet scheduling and interference between communicating nodes caused by the broadcast nature of radio propagation.
