Authentication, authorization and accounting (AAA) in hybrid ad hoc hotspot's environments

摘要: Wireless LAN (WLAN) is rapidly growing as a popular technology for ubiquitous communication, where Internet access being standard commodity. The demand in WLAN technological development to provide high quality and secure mobile users using their portable devices. Nevertheless, still restrictive, it requires the presence of communication range points. Moreover, security this network posing major challenge its usage. Hybrid ad hoc networks appear an attractive solution public hotspots applications, allowing achieve independent existence points ranges. Since effective Authentication, Authorization Accounting (AAA) are great importance wireless access, paper we propose novel architecture that provides efficient AAA among clients applications. Our uses hybrid concept considers service provider single point contact all transactions. We adapt IEEE 802.11i environment order set up authenticated links on layer 2, achieving well confidential data transfer. necessitates fixed infrastructure between authentication server, introduce cross-layer interaction with routing virtual through employing clustering mechanism. validate our proposed simulation. Through analyzing obtained results, give some performance estimates show advantages approach.
