  Abstract

This paper proposes a 'secure node' to be robust against network-based DoS attacks. The secure node selectively accepts new sessions based on the Zipf's law while a link is in the overload state. Our scheme calculates a threshold value for overload state, and provides a dynamic service mechanism for enhancing availability of a web server. The simulation results show performance improvement of the proposed scheme in terms of completion/connection ratios.
