Challenges in measuring wireless networks
Tristan Henderson
Collecting real data from wireless networks is useful for many
reasons, including application and protocol development, network
management, and network security. But collecting such data in a
wireless environment is more problematic than in a switched wired
network: the need to measure and monitor other contending networks,
networks in other channels, networks using other media access
protocols, and the vagaries of radio transmission can all lead to
incomplete data.
This talk will outline some of my experiences with wireless
measurement, including 802.11 security, mobility modeling and studying
the sociology of mobile computing users. I will then discuss some of
the remaining challenges in measuring wireless networks, including
future cognitive radio networks.

Tristan Henderson is a Lecturer in Computer Science at the University
of St Andrews. His research interests include wireless network
measurement, network economics and multiplayer networked games. He is
co-I of the CRAWDAD wireless data archiving project, which currently provides 23
wireless datasets to a community of over 500 users. He also serves on
JANET's Wireless Advisory Group and is a TPC member for this year's
IMC workshop on wireless measurement (IM4Win).
