On evaluating the latency in handing over to EAP-enabled WLAN APs from outdoors

Security has always been an issue with 802.11 WLANs despite their massive deployment across the cities. EAP has been widely endorsed by many businesses as a more recent and robust security protocol. This paper evaluates the delay incorporated by EAP-enabled WLAN APs when used from the outdoor environments. This evaluation is in relation with the performance of already deployed WLAN APs from vehicles moving at usual vehicular speeds for supporting broadband and on-road safety applications. As an initial step in evaluating EAP in vehicular setup, this paper examines the amount of latency that would be introduced if EAP-enabled APs are used from the outdoor environments. We perform an experimental evaluation of the latency in handing over to an EAP-based WLAN AP from outdoors at stationary and low mobility conditions.
