Using OLSR for Streaming Video in 802.11 Ad Hoc Networks to Save Bandwidth
J. Mart, Vaidy S Sunderam · 2007
Mobile ad hoc networks are prone by nature to path breaks and reconnections. Routing protocols such as OLSR that provide topology information with a minimum delay to the quick reconfiguration of path breaks are desired. Applications and protocols should be able to adapt to the dynamics of these networks. However, this is not true for most applications and protocols. For example, a video streaming server does not become aware of the path break because it does not interact with lower layers that inform about this event. As a result, important resources such as battery and bandwidth are not used eciently, and TCP connection failures happen frequently. In this paper, we present a proxy based solution to detect path breaks and reconnections using the proactive OLSR protocol for ongoing streaming sessions and we do corrective actions at the application layer to lead a more ecient usage of the bandwidth during disconnections.
