Description: Wireless networks, including Wi-Fi infrastructure and mesh networks, are becoming ubiquitous. It is critical to measure these networks to gain a better understanding of the traffic on the networks, the way they are used, and the response of the networks to different traffic patterns. It is also important to monitor operational wireless networks to improve security, capacity planning, and trouble shooting. Wireless networks pose unique challenges to measurement, however. In this talk I survey some of these challenges and describe some of the efforts underway to improve our ability to measure and monitor operational wireless network
