Intelligent Probing Technique for Bandwidth Estimation in Wireless Network
Source: Dublin City University
With the development of broadband systems, multimedia communication in wireless networks has become very common. However, supporting multimedia applications over multiple users either require high bandwidth or a dynamic bandwidth utilization mechanism. This in turn calls for an efficient technique, that can estimate the available bandwidth in the network accurately over real-time. In this paper, the different estimation algorithms are analyzed and the performance of state-of-the-art estimation algorithm, 'Spruce', is evaluated by comparing with the actual measured bandwidth. The key characteristic found was that all the bandwidth estimation techniques themselves take up some amount of bandwidth, which not only results in inaccurate estimation, but also takes up precious bandwidth resource.
