LAID: Load-Adaptive Internet Gateway Discovery for Ubiquitous Wireless Internet Access Networks

Ubiquitous wireless Internet access is to connect all devices to the Internet at any time and any place. To achieve this ubiquitous wireless Internet, we consider integrating the Internet and mobile ad-hoc networks. One of the most important issues in ubiquitous wireless Internet access is to find an efficient and reliable Internet gateway. We propose a load-adaptive hybrid Internet gateway discovery approach that can exploit network conditions. The loadadaptive hybrid 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 can reduce discovery overheads and improve end-to-end delay and delivery ratio than existing discovery schemes.
