Abstract:
In the recent years, the number of increased Wi-Fi networks and Wi-Fi-enabled devices shows how fast Wi-Fi technology is growing. Since a single network provider is usually not able to ensure Wi-Fi coverage for its own users across many geographic locations, we need Wi-Fi roaming. Eduroam is a Wi-Fi roaming system, which allows a user of a domain to access wireless resources in another domain with the unique credential of the user managed in the original domain. The authentication process in Eduroam is based on the hierarchical tree structured Remote Authentication Dial-In User Service (RADIUS) servers over wide area networks. Existing RADIUS-based tree structure of Eduroam is not self-configurable; joining/leaving of node is not automatically handled by the existing approach and it takes high communication delay as well. In order to improve the scalability of Eduroam with self-configurable feature and reduce communication delay as compared with tree structure-based Eduroam, we hereby proposed a Scalable & Self-configurable Eduroam by using Distributed Hash Table (DHT). Through a prototype implementation, we showed that the proposed system supports high scalability and high fault tolerance.
