ASWN 2004 is the fourth workshop on Applications and Services in Wireless Networks. The previous events were held in France and Switzerland, and in 2004 the workshop takes place in the United States for the first time, on the Boston University campus.

ASWN 2004 aims at investigating new developments in wireless networks focusing on applications and services. The workshop provides three-day presentations of peer-reviewed and invited papers from academia and industry. Presentations will address both theoretical and practical aspects of leveraging wireless and mobile environments. The technical program is preceded by a one day of tutorials and concludes with a Networking Reception event.
