Tactical wireless networks operate in complex environments with various resource constraints as well as constant link-state changes. These network topologies are predominantly based on some flavor of adhoc network design in order to accomplish rapid deployment goals. Utilizing the ns-3 simulator and a small tactical network topology with 50 nodes we evaluate the performance of both voice and video transmissions. A combination of nix-vector routing and link-state tables are used to create dynamic routing within the simulation. Then the performance of a SIP based real-time audio and video application in an adhoc network is analyzed. Additionally, we have implemented QoS in ns-3 to support traffic prioritization as needed by voice and video applications. Finally we compare the performance of the real-time voice and video applications using different traffic model.
