Figure 10From: Seamless internet 3G and opportunistic WLAN vehicular connectivityCumulative distribution function of the time spent connected to 3G and WLAN. Time spent by a vehicle using only the 3G network in a WLAN-to-3G-to-WLAN scenario (a) t-multihop = 2 and (b) t-multihop = 3. Time spent by a vehicle using also the WLAN network in a 3G-to-WLAN-to-3G scenario (c) t-multihop = 2 and (d) t-multihop = 3.Back to article page
