Performance study of a video application over multi hop wireless networks with statistic-based routing (work in progress)

Abstract

In recent years, technologies like Ultra Wideband (UWB) were developed that can be used to boost the data rate of wireless nodes to a new level. The higher data rate makes wireless networks capable of transporting multimedia content for real time applications like In Flight Entertainment (IFE), surveillance applications, or structural health monitoring. In this paper we measure and simulate the performance of a video application for IFE over a high data rate multi hop wireless network using a Directed Diffusion based routing protocol. Therefore, we take a look at the perceived video quality instead of focusing solely on the packet delivery ratio. Furthermore, we discuss the parameters of the Statistic-Based Routing (SBR) protocol which are relevant for this particular application and focus on their impact on the video quality during topology changes. © IFIP International Federation for Information Processing 2009.
