The advancement of mobile telecommunication and wireless technologies is required to provide local but familiar services in daily life, which has not been satisfied through the global services on the Internet. In retail business under evolving market, users request access to unknown but appropriate services based on their preference and situation, and retailers need to be aware of the current requirements of the majority of consumers in specific local trade areas. Because of the transience of the requirements of the users in their trade-areas, the services require being temporary and having the time limit. Therefore the areas of the services need to become narrower with the time. The concept of the service oriented community has been proposed to satisfy both the users and the retailers requirements. It consists of members in the specified area based on services, and they cooperate with each other in order to get mutual benefits. For realization of the service oriented community, the systems require flexibility for the effective provision of the services and fault tolerance for the stable service. In the service oriented community system, the Time Distance has been introduced as the efficient measure of the distance between the users and the retailers. The Time Distance Oriented Service System architecture has been proposed to satisfy these requirements for flexible and stable services, where the nodes are autonomously distribute services and reduce the service area based on the time distance. Here autonomous cooperation technique for achieving fault tolerance is proposed in order to satisfy the requirement of high service availability.
