Group 3 Characterization of Wireless: Network layer and above

Wired vs Wireless Compare wired to wireless behavior –Applications different? –Changes user behavior? How much delay people willing to pay for convenience of wireless?

Broader measurement Comparable measurement studies –Across wide variety of environments –Across several places, several times What is common across all apps, all places, all times? What is different?

Cross layers How do you correlate measurements of low-layer behavior with behavior of higher-level protocols or of users? In what ways do chipset, firmware version, driver version, OS, affect behavior of network (transport, network, MAC layers)

New applications Today: –WiFi laptops Tomorrow: –VoIP devices –Home/entertainment Multimedia (networked video player, cameras, …) Gaming devices –Embedded devices Security cameras, door locks Building control systems

Beyond WiFi How do our measurement studies apply to bluetooth, , …. How can our tools apply to studies of those networks?
