Electronic business in general and mobile commerce in particular offers a new roadmap for a business enterprise to gain strategic competitive advantages through up-to-date information and technology management. For mobile workers it offers a new avenue for a new knowledge-based economy, building upon the advanced hardware and software technologies.

Mobile Commerce M-Commerce comprises applications and services that are accessible from Internet-enabled mobile devices. It involves new technologies, services, and business models. While it is different from traditional e-Commerce it can also be seen as an extension of e-Commerce in the sense that it, among others, makes e-Commerce available in a modern way to new application areas and to a new set of customers.

The Internet is on its way to leave traces in all aspects of our life independently of where we are. Already today, mobile phones and PDAs become an indispensable part of our life as a source for all kinds of information and services and, especially, as our permanently available interface to our environment. Very soon they will turn into widespread intelligent assistants capable of anticipating many of our wishes and needs, such as automatically arranging for taxis to come and pick us up after business meetings or providing us with summaries of relevant news and messages left by colleagues. But, for all these changes to happen, key issues of interoperability, usability, security, and privacy still need to be addressed.

The Techniques and Applications for Mobile Commerce (TAMoCo) conference series is going to address these issues. It provides scientists, practitioners, and students a platform to discuss the latest trends in the exciting above mentioned areas.

This book is structured into three parts:

Part I: Wireless Technologies for the Extended Enterprise: Current State and Future Developments

The aim of part I is to analyse the state of the art and to stimulate discussions about future trends and technologies with respect to architectures that support business-to-employee and/or business-to-customer relations.

Nowadays, traditional office and business work is increasingly being performed in mobile environments, i.e. outside of offices, at the customer's location or on the road, where notebooks or handheld devices are used instead of PCs – often without access to high-bandwidth networks. However, users expect all services, information and tools they employ in their offices or at home to remain available to them in the mobile environment, too. Moreover, mobile solutions are expected to employ mobile technology with an added value regarding, e.g. personalization issues or context- and location-dependent information and services.

Part II: E-Service Environments: Aspect-Oriented Techniques and Mobile Devices

This part brings together approaches related to e-Services and/or mobile services and aspect-oriented techniques both from industry and academia. It provides an appropriate environment to discus the benefits of aspect-oriented techniques in e-Services systems, as well as in mobile environments, and problems and challenges that particularly arise during the practical combination of these fields.

Part III: AutoMoCo: Autonomic Computing and Mobile Commerce

Autonomic Computing is an area of research looking at imbuing software with dynamic behaviours based on its operating environment. In mobile commerce, autonomous behaviours could be used to help solve the issues of an ever-changing deployment environment, and the differing requirements for actors in commerce transactions. Since its introduction at the beginning of this millennium, autonomic computing has seen major uptakes by a range of communities including enterprise software developers, and grid computing groups to name just a few. In this part active researchers and practitioners will report on novel or ongoing research into autonomic computing and its application of mobile computing with focus on mobile commerce.

Acknowledgments

The organizers would like to express their gratitude to the authors, for submitting their work to TAMoCo 2008, and to the Program Committee, for providing very thorough evaluations of the submitted papers as well as for the discussions that followed under significant time constraints. We also would like to thank the invited speakers and the panel moderator for their efforts in contributing to the success of the conference.

On the organizational side a lot of people have been there from the start of these series and hence we thank them profusely. One of them is the Tilminator Mr. T. Bitterberg although we are not sure about his Lederhosen. Other highly supporting people include Mrs. MacDonald, Ms. Campbell, Ms. Watson, Lee, Darren and last but not least all the staff at Roderick Dhu and Ruarg.
