LAID: Load-adaptive Internet gateway discovery for ubiquitous wireless Internet access networks

Abstract

Ubiquitous Internet connectivity is to connect all devices to the Internet at any time and any place. To achieve this ubiquitous Internet connectivity, we consider integrating the Internet and mobile ad-hoc networks. One of the most important issues in the ubiquitous Internet connectivity is to find an efficient and reliable Internet gateway. We propose a load-adaptive Internet gateway discovery approach that can exploit network conditions. The load-adaptive Internet gateway discovery scheme dynamically adjusts a proactive area according to network traffic. Among the candidates, a serving gateway is selected based on offered load. The simulation results show that our discovery scheme outperforms existing discovery schemes. © Springer-Verlag Berlin Heidelberg 2006.
