The problem of multicasting in wireless multihop networks was studied in this dissertation. Nodes in the multicast routing structures were classified into different classes based on their roles in the multicast routing structures. Optimal multicast routing strategies for different classes were analyzed using the most accurate interference model. Based on the analyses, two algorithms to create interference-aware multicast routing tree and three algorithms to create interference-aware multicast routing mesh were proposed. The proposed multicast routing structures were evaluated using wireless network simulations. To improve the credibility of the wireless network simulations, a frame-level bursty link model was proposed and implemented in ns-3 network simulator. The results showed that, by taking interference into account when building multicast routing structures, the proposed multicast routing structures provided improved performance over other multicast routing structures that do not consider wireless interference when building multicast routing structures.
