This volume contains the proceedings of the Fifth International Workshop on Wireless Information Systems (WIS) held in conjunction with the Eighth International Conference on Enterprise Information Systems in Paphos, Cyprus in May 2006. This year’s edition of the WIS workshop builds on the success of the four previous WIS workshops (Ciudad Real (2002), Spain; Angers (2003), France; Porto (2004), Portugal; and Miami (2005), USA). The aim of this workshop is to serve as a forum for researchers and practitioners to meet and share expertise in wireless information systems. Wireless information systems represent an emerging field, and the papers contained in this volume reflect on the multidisciplinary character and broad spectrum of this area. Some of the papers address challenges posed by wireless information systems such as security and privacy issues, quality of wireless information, storage and mobility management. Other papers report on experiences developing mobile commerce
applications and new communication technologies such as RFID. All these applications are based on the unique properties of handheld wireless mobile devices that are equipped with a variety of communication capabilities. We would like to take this opportunity to thank all authors and reviewers for their valuable contributions to WIS 2006, and we wish them a successful continuation of their research. We also want to thank the ICEIS team – especially Joaquim Filipe and Vitor Pedrosa – for hosting our event in the more global frame of the international ICEIS conference series, and finally we want to thank the general workshop chairs Slimane Hammoudi and Olivier Camp for their hard work in making WIS a successful event. We wish all authors and attendees an exciting workshop, and a pleasant stay in the lovely historic place of Paphos.
