Abstract
Mobile communications technologies have reached a significant penetration today and the development of technologies and applications is still emerging. The Internet has become the major core network around which several wireless access networks are inter-connected. These access networks are not just single wireless links, but are becoming diverse and complex. For example, sensors are connected via sensor networks, cars connect via mobile ad hoc networks, and users in areas without GSM/UMTS coverage might only be reached via satellites. Moreover, the requirements to mobile communications are increasing. Security is a major concern in such networks and small wireless/mobile devices need to save as much power as possible to ensure long lifetimes. The 4th International Conference on Wired/Wireless Internet Communications (WWIC 2006) took place at University of Bern (Switzerland) from May 10 to 12, 2006. WWIC 2006 addressed relevant research issues such wireless networks, UMTS and OFDM, mobile ad hoc networks, power saving and sensor networks, voice and video over wireless networks, mobility, transport protocol issues as well as signalling, charging, and security. The goal of the conference was to present high-quality results in the field. The international conference program committee selected 29 papers out of 142 submissions for conference presentation. Finally, five 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.
