Special Issue: The IADIS Wireless Applications and Computing (WAC) Conference GUEST EDITORIAL PREFACE JITWE 4(1) Jörg Roth, University of Applied Sciences, Germany Enormous developments in wireless technologies in recent years enable both researchers and industries to create new, innovative and powerful wireless and mobile applications, services, middleware platforms, and application frameworks. The IADIS Wireless Applications and Computing (WAC) conference addresses several topics related to theory and practice within wireless networks and mobile computing. Looking at recent work, researchers can identify the main categories related to mobile and wireless applications. To read the preface, please consult this issue of IJITWE in your library.

PAPER ONE A Concept for Mobile Ad-Hoc Messaging Networks (AMNet) Stefan Stieglitz, University of20Potsdam, Germany Christoph Fuchß, Virtimo Webbased Applications, Germany Sascha Stöckel, Brandenburg University of Applied Sciences, Germany Christoph Lattemann, University of Potsdam, Germany This article shows an innovative approach for an ad-hoc messaging network (AMNET) which uses simple store-and-forward message passing to spread data asynchronously. This approach primarily focuses on application specific needs that can be covered by simple message passing mechanisms. In this paper, the authors will describe a powerful network by using simple devices and communication protocols on the basis of AMNETs.

PAPER TWO Viticulture Zoning by an Experimental WSN P. Mariño, University of Vigo, Spain F.P. Fontán, University of Vigo, Spain M.A. Domínguez, University of Vigo, Spain S. Otero, University of Vigo, Spain Biological research in agriculture needs a lot of specialized electronic sensors in order to fulfill different goals, such as: climate monitoring, soil and fruit assessment, control of insects and diseases, chemical pollutants, identification and control of weeds, crop tracking, and so on. That research must be supported by consistent biological models that are able to simulate diverse environmental conditions, in order to predict the right human actions before risky biological damage could be irreversible. In this paper an experimental distributed network based on climatic and biological wireless sensors is described. Then the experimental network for field automatic data acquisition is presented. The design of the wireless network is explained in de tail and future developments and conclusions are stated.

PAPER THREE A Linked Neighboring Leaves N-Tree to Support Distance Range Search Faïza Najjar, National School of Comp. Science, Tunisia Hassenet Slimani, Faculty of Sciences, Tunisia Mobile query processing is, actually, a very active research field. Range and nearest neighbor queries are common types of queries in spatial databases and location based services (LBS). In this paper, we focus on finding nearest neighbors of a query point within a certain distance range. An example of query, frequently met in LBS, is "Find all the nearest gas stations within 2 miles neighborhood of his/he r current location". The authors propose two approaches for answering such queries. Both are based on a recent indexing technique called N-tree. The first one is a branch and bound approach, whereas the second, called 'neighborhoods scanning', is based on a variant of N-tree, Leaves-Linked N-tree (LLN-tree). Both techniques are presented, illustrated, and evaluated. To obtain a copy of the entire article, click on the link below. http://www.infosci-on-demand.com/content/details.asp?ID=32040

PAPER FOUR A Location-Aware Access Control Model for Mobile Workflow Systems Michael Decker, University of Karlsruhe, Germany Workflow management systems (WfMS) are a special class of information systems (IS) that support the automated enactment of=2 0business processes. Meanwhile there are WfMS which allow the execution of tasks using mobile computers like PDA with the ability of wireless data transmission. However, the employment of workflow systems, as well as mobile technologies comes along with special security challenges. One way to tackle these challenges is the employment of so location aware access control to enforce rules that describe from which locations a user is allowed to perform which activities. The data model behind access control in termed access control model (ACM). There are special ACM for mobile information systems (IS), as well as for WfMS but no one that addresses mobile and workflow specific aspects. In the article the authors therefore discuss the specific constraints such a model should be able to express and introduce an appropriate ACM.

PAPER FIVE Context-Aware Recommender Systems in Mobile Scenarios Wolfgang Woerndl, Technische Universitaet Muenchen, Germany Michele Brocco, Technische Universitaet Muenchen, Germany Robert Eigner, Technische Universitaet Muenchen, Germany In this article, the authors give an overview of ideas for integrating context in recommender systems in general and specifically in various mobile application domains. The main case study is an approach for vehicular ad-hoc networks (VANETs). The system recommends gas stations based on driver preferences, ratings of other users and context information such as the current location and fuel level of a car. The researchers explain the main design issues behind our recommender. Our approach first filters items based on preferences and context, and then takes ratings of other users and additional information into account. The authors also outline other mobile scenarios for contextualized recommender systems.

Mission of IJITWE: The main objective of the International Journal of Information Technology and Web Engineering (IJITWE) is to publish refereed papers in the area covering information technology (IT) concepts, tools, methodologies, and ethnography in the contexts of global communication systems and Web engineered a pplications. In accordance with this emphasis on the Web and communication systems, this journal publishes papers on IT research and practice that support seamless end-to-end information and knowledge flow among individuals, teams, and organizations. This end-to-end strategy for research and practice requires emphasis on integrated research among the various steps involved in data/knowledge (structured and unstructured) capture (manual or automated), classification and clustering, storage, analysis, synthesis, dissemination, display, consumption, and feedback. The secondary objective is to assist in the evolving and maturing of IT-dependent organizations, as well as individuals, in information and knowledge based culture and commerce, including e-commerce.
