Autonomous cooperation technologies for achieving real time property and fault tolerance in Service Oriented Community system

The advancement of wireless communication and mobile telecommunication has made mobile commerce possible. In the retail business under the evolving market, the users would like to utilize the appropriate services based on their preference and situation continuously. The service providers need to grasp the current requirements of the majority of the users in the local service area in order to provide the effective service for the current local majority of the service area.

Here, Time Distance Oriented Information Service System has been proposed to achieve flexibility in collecting the users' marketing information in the area based on services. In the community system, the key idea is autonomous cooperation among nodes to satisfy the requirements. Here, Autonomous Synchronization Technique and Autonomous Cooperation Technique are proposed to satisfy real time property and fault tolerance respectively. The effectiveness of these technologies is shown at the end.
