5th IEEE Workshop on Pervasive Wireless Networking (PWN 2009) Message from the workshop co-chairs

It gives us great pleasure to welcome you to Galveston, Texas and the 2009 IEEE PerCom Workshop on pervasive wireless networking (PWN09). Wireless connectivity, mobility support, location awareness, and integration of wireless networks to the Internet are key research challenges in pervasive computing and communications. With the advent of inexpensive wireless solutions such as WiFi, WiMAX, Bluetooth, ZigBee, and RFID, a number of challenges arise when these protocols are applied to wireless PAN, home networking, wireless LANs, wireless mesh networks, wireless MANs, and wireless broadband. Exploitation of emerging wireless technologies such as transmit power and rate control, spectral agility, adaptive carrier sensing, cooperative communication as well as application of existing technologies to new applications such as wireless mesh networks and sensor networks are emerging, important research areas. Therefore, we are pleased to present twelve high-quality papers contributing to the theory, practice, and evaluation of wireless networks for pervasive computing. We would like to congratulate the authors of accepted papers and also express our gratitude to the Program Committee members for their wonderful job in helping us field an excellent set of papers for the workshop. This year, among those accepted papers, we have a number of invited papers in the emerging areas of pervasive wireless networking, and would like to thank these authors for accepting our invitation. We hope that participants of PWN09 hear about up-to-date issues and challenges in pervasive wireless networking area and find the workshop more useful for their future research. Once again, we hope you enjoy this collection of papers and wish all of you a pleasant stay in Galveston, Texas.
