A Study on Differentiated Service for Mobile Application Support

Abstract

When the wired network technologies are getting matured, the whole network trends are to develop “broadband” and “mobile” network infrastructure, and to enable everyone access the Internet everywhere. Therefore, the wireless network technology is a hot topic in current network research. However, there are many problems in the wireless network, including mobility of mobile hosts, battery power, high packet loss rate, and lower bandwidth that never appear in the wired environment. In order to provide good Quality of Service(QoS) in wireless environments, there are still many problems needed to be solved.
