multi-hop buffering and adaptation for video-based sensor networking applications
As video sensor networks become more widely deployed, mechanisms for adaptively transmitting video data within the network are necessary because of their generally large resource requirements compared to their scalar counterparts. The key features of such networks include (i) many sources can inject video into the network that is destined for the same sink and (ii) nodes that participate in routing can also potentially work collaboratively for the benefit of the entire system. In this paper, we propose a multi-hop buffering and adaptation framework for video-based sensor networking applications. We explore several approaches in this framework and compare their performance with traditional IP-based video streaming technologies. Our experiments show that these approaches outperform traditional technologies in video quality, bandwidth waste, and bandwidth sharing fairness.
