Editorial Wired/wireless Internet communications Next generation mobile networks are expected to be based on Internet core networks and wireless access networks. The need for efficient merging of the wired and wireless infrastructure as well as new multimedia services and applications require novel network architectures, protocols and control mechanisms. The topics have been discussed during the 3rd International Conference on Wired/Wireless Internet Communications (WWIC 2005), which took place

WWIC 2005 addressed relevant research issues such as network design, traffic engineering, transport protocols, cross layer interaction, inter-working of wired and wireless networks, wireless multi-hop networks, handover and mobility management, quality-of-service, multimedia services and economical ones. The goal of the conference was to present high-quality results in the field. The international conference program committee selected 34 papers out of 117 submissions. Finally, 12 papers from the ones presented at the conference have been selected for this special issue. The selected papers have been improved based on the conference reviews and extended in order to present latest research results in more detail. An important topic of WWIC 2005 has been the issue how to support multimedia applications over wired/wireless networks. Jeong-Yong Choi and Jitae Shin propose a "Content-Aware Packet-Level Interleaving Method for Video Transmission over Wireless Networks". This mechanism considers the importance of the video content to ensure for interleaving in order to improve the overall video quality compared with content-blind interleaving methods. Another approach to improve video quality over wireless LANs is pursued by Francisco M. Delicado, Pedro Cuenca, and Luis Orozco-Barbosa in their paper "QoS Mechanisms for Multimedia Communications over TDMA/TDD WLANs". The authors propose to perform bandwidth allocation in order to guarantee the performance requirements of multimedia applications. The article "A Performance Study on Service Integration in IEEE 802.11E Wireless LANs" from Frank Roijers, Hans van den Berg, Xiang Fan, and Maria Fleuren evaluate the IEEE 802.11e Quality-of-Service (QoS) differentiation 0140-3664/$ -see front matter Ó
