A Dynamic Threshold Technique for XML Data Transmission on Networks

Abstract

XML is increasingly being used to transmit data on networks but it is a verbose format. One may employ a middleware to enhance performance by minimizing the impact of transmission time [1, 2]. Normally, to reduce the amount of data sent the XML documents are converted to a binary format using a compression routine such as XMill [3]. However while this would reduce the amount of data, it results in an increase in the CPU time. We present a technique to decide if it would be transmitting the XML document as a compressed document or not depending on a threshold that we first establish. Experimental results show our method is superior to the NAM method [1]. The simulation results shows that for an example of a 4.5 MB XML file in our method will make the CPU time decreasing 22.69% and total transition time will save 4.61% in comparison with the method described in [1].
