This book constitutes the refereed proceedings of the IFIP-TC6 Eighth – ternational Conference on Personal Wireless Communications, PWC 2003. PWC 2003 is the ?agship conference of the IFIP Working Group 6.8, Mobile and Wireless Communications, and is the premier international forum for discussions between researchers, practitioners, and students interested in the symbiosis of mobile computing and wireless networks. It is a great pleasure to present the PWC 2003 technical program. This year the conference received 115 submissions from 27 countries indicating that PWC is a reference conference for worldwide researchers from the wireless and mobile community. With so many papers to choose from, the Technical Program Committee’s job, to provide a conference program of the highest technical quality, was challenging and time consuming. From the 115 submissions, we ?nally selected 34 full papers and 15 short papers for presentation in the conference technical sessions. The conference technical program was split into three days, and included, in addition to the 49 refereed contributions, 4 invited papers from top-level researchers from the mobile and wireless community. To give researchers the opportunity to present ongoing work, and the novel ideas they are starting to explore, we included in the technical program two work-in-progress sessions and two novel-ideas sessions. The technical program also included a poster session devoted to presenting ongoing research projects on wireless and mobile communications.
