With the development of wireless network technology and multimedia technology, multimedia applications of MANET have gained more and more attention. How to ensure the QoS of video communication in multi-hop network is an urgent key problem. Multi-path streaming is a useful way to improve the quality of wireless video transmission. In this paper, we first analyze the routing mechanism of AOMDV and SMR. Then we use NS2 to generate different scenario files using different movement modes, and through forwarding scalable video contents, we test the performance of AOMDV and SMR. At last, we evaluate their performance through packet delivery ratio, average end-to-end latency and normalized routing overhead.
