Bandwidth Estimation in Wireless Lans for Multimedia Streaming Services Conference Paper uri icon


  • The popularity of multimedia streaming services via wireless networks presents major challenges in the management of network bandwidth. One challenge is to quickly and precisely estimate the available bandwidth for the decision of streaming rates of layered and scalable multimedia services. Previous works based on wired networks are too burdensome to be applied to multimedia applications in wireless networks. In this paper, a new method, IdleGap, is suggested to estimate the available bandwidth of a wireless LAN based on the information from a low layer in the protocol stack. We use a network simulation tool, NS-2, to evaluate our new method with various range of cross traffic and observation times. Our simulation results show that IdleGap accurately estimates the available bandwidth for all ranges of cross traffic (100Kbps-1Mbps) with a very short observation time of 10 seconds. © 2006 IEEE.
