This Industrial track is organised in conjunction with the fourth Mobile Data Management conference (MDM’02), organised at Monash University, Melbourne. The MDM conference aims at investigating core issues related of data mobility and focusing on the challenges and opportunities for data management and data access technology in the rapidly evolving world of mobile, pervasive, ubiquitous, invisible and wearable computing.
This Industry track provides a complement to the MDM conference as it addresses the industrial experiences with mobile data management. Such experiences can be industrial applications, prototypes, experiences, and standards (or proposed standards). This includes location based services, sensor networks and sensor-based services, QoS and QoS-based services, provisioning of terminals and services, user profile and policy management, peer-to-peer technologies, search engines, ontologies and ontology search mechanisms, mechanisms for managing streaming, caching and data encoding, encryption and compression, adaption of data to mobile devices, distributed database technologies, and other associated topics e.g. user interfaces, protocols, etc.
For 2002 Industry track we received several submissions. Each paper has been reviewed by the two Industry track co-chairs, namely Johan Hjelm and Zahir Tari.
At the end of the process, we selected six papers describing implementations and practical results in the field of mobile data management. Below is a brief description of these papers.
· The first paper
is from K. Hendricksen, J. Indulska, and A. Rakotonirainy and it is about the
generating of context management infrastructure from context models. This paper
describes a context modelling approach that offers a means for developers to
describe and program with context at a high level, without the need to consider
issues related to context gathering, management or representation. A detailed
mapping process (which transforms high-level context models to management systems)
is proposed.
· The paper from Ali Paasimaa is about the design of a distributed Fleet Management over GPRS with Solid FlowEngine. Solid FlowEngine in part provides platform independent functioning, enables transactions to be executed while offline and guarantees transactional consistency throughout the whole network. The article provides an interesting comparison between an IP-based GSM network protocol GPRS with traditional circuit-switched technologies. The paper also describes Buscom Palette (a traffic information management system) built on Solid FlowEngine.
· The third paper reports from ongoing activities in the Technical Committee Human Factors of the European Telecommunication Standards Institute (ETSI TC HF), performed under the European Commission’s eEurope Initiative by major industry representatives. It is co-authored by B. von Niman, M. Schneider-Hufschmidt and H. Kiljander. This paper proposes a basic approach that focuses on simplifying the learning procedure for end users, thereby allowing for reuse of basic knowledge between different terminal devices and services, leading to a faster and easier adoption of new technologies.
· The fourth paper is about a standard spoken command vocabulary for ICT devices and services. This paper is co-authored by B. van Niman, C. Chaplin, J-A Collado-Vega, L. Groh, S. McGlashan, W. Mellors, and D. van Leeuwen. The proposed approach focuses on simplifying the learning procedure for end-users, thereby allowing for reuse of basic knowledge between different terminal devices and services, leading to a faster and easier adoption of new technologies. In particular, the paper discusses the importance of involving potential users of such products in this process, rather than relying on expert judgment alone to determine what the standard commands should be.
· The fifth paper is about mobile multimedia content search using RDF and it is co-authored by H. Sumino, N. Ishikawa, T. Kato, Y. Yu, Z. Zhu, and J. Hjelm. This paper describes a multimedia content search prototype system for mobile phones. This system is implemented over P2P network as a distributed search system and consists of distributed search nodes and the proxy node that provides the interface for mobile phone. Resource Description Framework (RDF) is used as the technology for describing metadata and a Java content search system for mobile multimedia content search is described.
· The last paper
describes a system model and algorithm for content-based routing in mobile peer-to-peer
information search. It is co-authored by Z. Zhu, Y. Yu, J. Hjelm, N. Ishikawa,
H. Sumino, and E. Omata. The proposed approach enables a knowledge based to
be constructed in each node of Hop-based Layer; content information to be forwarded
from nodes of a specified Hop -based layer to their management node of 1-hop
upper layer in turn until the requesting node; and routing priority to a path
is decided based on the calculation result of files distribution with all nodes
of the path.
We glad to accept such good quality papers and we hope that they will provide the readers with the most recent practical and industrial developments in the area of mobile systems. We also hope that you will enjoy the presentations of the Industry track and we are looking forward to see you again in the future events.
