Mobile information community develops quickly, as mobile telecommunication technology matches to the third generation. XML-based GIS becomes a global standard and the foundation. Recent developed Geography Markup Language (GML) allows integration of GIS location-based services, telematics, and intelligent transportation systems. In this paper, we propose a tourism information system for support...

This paper suggests an architecture of DNS service system for IPv6 mobile ad-hoc network connected to the Internet. The DNS resolution of DNS names of mobile nodes within mobile ad-hoc network is performed by multicast DNS and that of DNS names of nodes in the Internet is performed through DNS autoconfiguration of recursive DNS server. In the former, each mobile node plays a role of DNS name se...

This paper presents an approach based on wireless web and dialogue system convergence for multimodal, multimedia communication services over converged networks. It uses a unique event-triggered service delivery method that separates service interaction and wireless web-based service delivery. Our approach results in an architecture of WAP-based, locationindependent, wireless service monitoring,...

We present the architecture of an enterprise mobile service gateway for secure mobile access to distributed, autonomous, and heterogeneous enterprise data and services using browser-based thin-client. Our goal is to address key issues associated with mobile access to enterprise information, while minimizing the cost of service integration by leveraging existing infrastructure and business appli...

We present a framework for Web services provisioning in a hybrid environment of fixed and mobile computing resources. Several obstacles still hinder the seamless provisioning of Web services in mobile environments. Examples of such obstacles are: throughput and connectivity of wireless networks, limited computing resources of mobile devices, and risks of communication channel disconnections. In...
