Abstract
The advancement of mobile telecommunication has made mobile commerce possible. Reliable communication between the retailers and the users is required for the provision of the services. Real-time property is also required for the marketing of the users' requirements and the provision of the local majority based services. Achieving assurance for these requirements under the evolving situation is required. Time distance, which changes with the situation is introduced as the efficient measure of the distance between the users and the retailers. The time distance oriented service system has been defined to satisfy real-time property and reliable communication in the local trade area. The system architecture, and the autonomous interactive communication between the users and the retailers are presented. Here, nodes have autonomy for fading unnecessary and inconvenient information through time distance based communication among them both for the marketing and provision. The nodes also autonomously reduce the information service area for achieving further effectiveness. It is shown that this architecture and technologies realize assurance for the real-time properties and reliability and achieve effectiveness in mobile commerce.
