Securing Internet Gateway Discovery Protocol in Ubiquitous Wireless Internet Access Networks

摘要

Ubiquitous wireless Internet access networks (UWIANs) integrate mobile ad hoc networks into the Internet to achieve ubiquitous Internet connectivity. The Internet connectivity is provided by Internet gateways in the UWIANs. Most of the Internet connectivity research has not considered a malicious environment. However, UWIANs will not be able to succeed without an effective security solution due to wireless links and energy constraints. Thus, security is a critical factor to the success of ubiquitous Internet connectivity. In this paper, we propose a secure Internet gateway discovery protocol in order to provide the secure Internet connectivity. A registration mechanism is also proposed to secure a foreign network and an ad hoc mobile node when it connects within the network. The efficiency of the protocol is shown via simulation.
