摘要：With the prevalence of wireless video applications, QoS of wireless video transmission in resource-limited wireless networks attract more and more researchers’ attention. In network layer, how to perform video packet assignment in multipath routing is a key issue. In this paper, we develop a simple but efficient, priority based dynamic assignment algorithm for multipath routing. The idea of this algorithm is to assign packet to a suitable path dynamically based on the priority of a video packet, quality difference between different paths and coding structure of the streaming video sequence. Simulation results show that our novel algorithm outperforms single path routing algorithm and other multipath routing algorithms significantly in packet receiving and average PSNR performance.
