“…The concept of community division is originally proposed in [7], but the main purpose of community division in [7] is to improve the reliability. Since marketing application not a mission-critical but more of a common application, timeliness rather than reliability is more required by the users.…”

In the retail business under the evolving market, the users solicit to use the appropriate services based on their preferences. In addition, the service providers insist on seizing the current requirements of the users for customizing adequate services. Such requirements can not be satisfied with the conventional centralized system, due to the lack in flexibility. Autonomous Decentralized Community System has been proposed to realize for achieving such requirements. Community is devised as a group that constructed among wireless base stations, and each member of community collaborates with the others autonomously. Thus, the system realizes flexibility, but since the system has no centralized existence for system monitoring, improvement in timeliness is still considered as a remaining problem. In this paper, Autonomous Construction Technology is proposed to improve the timeliness of a community according to the number of nodes. The members of a community autonomously integrate and divide to adjust the optimal size of the community.

“…Generally, wireless ad-hoc based or cellular based CPS include time-distance oriented m-commerce services offered in towns/city [15], on-the-fly delivery of dynamic applicationoriented CPS, data sharing services providing environmental information gathered from static or mobile sensors attached to devices [21]. Examples of time-distance oriented m-commerce CPS are time-sales application [3] or restaurant discovery at lunch time by businessmen in certain area with common interests considering composite attribute (time-distance) and logical or physical attribute like user's preferences (price, cuisine, parking space, seats availability), location, service expiry time. Likewise, the examples of application oriented CPS include large file sharing (code distribution, streaming) in ubiquitous ad-hoc environment [29], [30].…”

SUMMARYLocation Based Services (LBS) are expected to become one of the major drivers of ubiquitous services due to recent inception of GPS-enabled mobile devices, the development of Web2.0 paradigm, and emergence of 3G broadband networks. Having this vision in mind, Community Context-attribute-oriented Collaborative Information Environment (CCCIE) based Autonomous Decentralized Community System (ADCS) is proposed to enable provision of services to specific users in specific place at specific time considering various context-attributes. This paper presents autonomous community construction technology that share service discovered by one member among others in flexible way to improve timeliness and reduce network cost. In order to meet crucial goal of real-time and context-aware community construction (provision of service/ service information to users with common interests), and defining flexible service area in highly dynamic operating environment of ADCS, proposed progressive ripple based service discovery technique introduces novel idea of snail's pace and steady advancing search followed by swift boundary confining mechanism; while service area construction shares the discovered service among members in defined area to further improve timeliness and reduce network cost. Analysis and empirical results verify the effectiveness of the proposed technique. key words: autonomous decentralized community system, community context-attribute-oriented collaborative information environment, community pervasive services, service discovery protocols, autonomous community construction, progressive ripple zone (PRZ)

“…[4] Since services provided by community network are time dependent, therefore, informing the users about validity of service with acute accuracy is of the essence. But time awareness of community services is highly dependent on timedistance attribute [3,4], and owing to its extreme nature of dynamism, the accuracy of service provision could be highly erroneous. Therefore, caching the validity time of service for effective and quality of situation-aware service provisioning, it is imperative for ADCS to accurately cache validity time of service keeping in view time lapse of service as well as any change in time-distance.…”

“…For example, in the retail business under evolving market, users are interested to search out attractive services based on their current situations and preferences; while to offer customized services, service providers are eager to grab the current requirements of local majority of users in the vicinity. [3] Due to these underlying overlapping requirements, information services considering users' preference and situation become significant one.…”

Recent headway in the domains of mobile communication and ubiquitous computing has given surge of interest to mobile commerce applications. Current information systems promote concept of information service provision to anyone, anytime and anywhere. Autonomous Decentralized Community System has been proposed to meet the varying requirements of users.In this paper, the decentralized search service is taken up as an application. This retrieves service in which the service offer end time has been decided beforehand. Needs of this application are the accuracy, the adaptability, and the improvement of the assurance is requested. There are two requirements in this service. First, it is to prevent the network being crowded with the request message from the node where SP that can enjoy serving doesn't exist. And, it is to prevent the stability of the entire system from decreasing to update cash information. To solve these, it proposed the Autonomous Construction Technology and the Autonomous Change Adjustment Technology.Simulation results demonstrate the effectiveness of proposed technology in terms of improvement in service assurance and confirms the trade-off between accuracy and system stability.
