It serves as the premier forum for presenting and discussing research results on networks, systems, algorithms, and applications supporting the symbiosis of mobile computing and wireless networking. Each year, the conference attracts about 500 researchers, practitioners, students, and executives. MobiCom 2005 will be held in beautiful Cologne, Germany. Technical Program. The program consists of a single track with 23 papers. The authors present cutting-edge results on various topics, such as new architectures, content-based and geometric routing, self-management, cross-layer optimization. The papers cover ad hoc networks, mesh networks, wireless sensor networks, WLANs, and cellular networks. A list of accepted papers can be found at http://www.sigmobile.org/mobicom/2005/program.html. Tutorials. Four tutorials will be offered: (a) Wireless sensor and actuator networks, (b) 802.11 WLAN MAC and smart antennas: issues and directions, (c) Security in sensor and ad hoc networks: perspectives and status, and (d) Wide area wireless networks: 3G and beyond. The conference will also feature two invited talks by leaders in our field: (a) "Secure, Natural Communications," by Jeffrey M. Jaffe, President, Bell Labs Research and Advanced Technologies, and (b) "Communicating Vehicles - Communicating Roadways: New Approaches to Driver Information and Road Safety," by Ralf Guido Herrtwich, Director Vehicle IT and Services Research, DaimlerChrysler AG. Cologne is very popular, especially in August due to World Youth Day 2005 taking place there. Because Pope Benedict XVI organizes this event, he will be in town just the week before MobiCom. Thus, we ask you to make your hotel and flight reservations as early as possible. For more travel info please visit http://www.sigmobile.org/mobicom/2005/travel.html.
