Distributed Retrieval of Wavelet Images Using Bandwidth Monitoring

1 See the demo site at http://www.cs.ualberta.ca/{~anup,~TeleLrn} ABSTRACT Limitations on the bandwidth to a server makes the retrieval of a large-size high-resolution image, even compressed, very time-consuming. To speed up this process we replace the retrieval process from a single server with the retrieval from multiple servers, i.e., simultaneously retrieving different part of an image from multiple server sites. In this paper, we present a blockbased distributed retrieval strategy for images compressed by the Embedded Zerotree of Wavelet coefficients (EZW) algorithm. The experimental results validate that blockbased distributed retrieval is an efficient strategy to speed up downloading.
