Design and implementation of SNS-based wireless LAN access sharing system

In order to receive mobile multimedia service cost-effectively, the smartphone user´s demand on free access to widely deployed wireless LAN (WLAN) systems has been greatly increasing. This is because 3G or 4G mobile networks are usually expensive, and slower than WLAN. Unfortunately, although secure WLANs are installed widely, they are usually not shared. In this article, we have designed and implemented secure WLAN sharing system using social network service (SNS). A new secure WLAN sharing model has been proposed in which the social trust strength between people is employed for secure WLAN access control.
