The paper presents a jamming resistant architecture for military applications of WiMAX (802.16) mesh network. The main idea is to use multiple base stations (BS), access points to the fixed core network. This will facilitate network survivability both in case of a BS destruction and in case of jamming. When the nodes are affected by jamming they can reroute to another base station if possible. The multiple BS architecture requires distributed scheduling as there is no single point of control that can execute centralised scheduling. A distributed scheduling algorithm, performing well in both jammed and nonjammed environment, is a key issue in implementation of the architecture. Several scheduling algorithms are considered in the paper: a static algorithm using the number of traffic flows in the node, dynamic load-dependent algorithms using two- and three-hop neighbour information. Finally, an algorithm based on finite field initial slot assignment is proposed. This algorithm uses two-hop information and is also load-dependent. Performance of different algorithms is evaluated with and without jamming. The finite field algorithm shows the best performance in both cases.
