This book constitutes the refereed proceedings of the 6th International Conference on Wired/Wireless Internet Communications, WWIC 2008, held in Tampere, Finland, in May 2008. The 18 revised full papers presented were carefully reviewed and selected from 67 submissions. The papers are organized in topical sessions on performance analysis of wireless systems, resource and QoS management, implementation techniques, mobility, cross-layer design, and wireless sensor networks.
