A Dynamic Congestion Control Based Multipath Routing Protocol for Video Transmission over Ad Hoc Networks
June 12-June 14
ISBN: 978-0-7695-3187-8
In wireless ad hoc networks, there are great challenges of supporting real-time video transmission due to the impact of frequent link interruptions, collisions, and bandwidth limitations and so on. Based on the analysis of the multipath routing and congestion control strategy, we propose a dynamic congestion control based multipath routing protocol (DccMR). DccMR establishes and maintains redundant multiple paths with very low routing overhead. A dynamic congestion control strategy is applied to adjust packets routing in a load-aware manner. When all shortest paths broken, a route update procedure will be initiated by the destination node, in which new paths will be reestablished whereas the video transmission will not be interrupted. Simulation results show that our protocol can decrease routing overhead significantly and improve the real-time video transmission quality.
