Figure 5From: WING/WORLD: An Open Experimental Toolkit for the Design and Deployment of IEEE 802.11-Based Wireless Mesh Networks TestbedsSequence number (SN) versus Round-Trip-Time (RTT) as reported by the ping command. Each point represents a single RTT value. This graph shows the Ethernet/Wifi transition (SN between 120 and 220), the WiFi/UMTS transition (SN between 270 and 305), the UMTS/WiFi transition (SN between 570 and 620), and the WiFi/Ethernet transition (SN between 770 and 780).Back to article page
