After a thorough study over different kinds of group-awareness theories in recent years, and combined with today's very popular service oriented architecture (SOA) technology, we propose a new group-awareness model which is based on services. SOA technology has many advantages, such as high efficiency, quick response, low expense, and so on. Hence, it is more convenient to depict the characteristics of the real world's group activities with SOA technology's loose coupling structure and dynamic-calculation property. It is believed that the structure of a group is not stable, and it changes along with the time, the completion of goals and other random factors. In the world of SOA, all things are encapsulated in services. Due to the concept of service, the ability to characterize the dynamic structure of a group is strengthened and the group-awareness model of dynamic-structure group becomes more suitable for the practical use. Moreover it is more easily and accurately that we can calculate the awareness intensity of individuals by the use of services composition tree than other related works. At the end of this paper, we discuss implementation and possible application domains of this model, then point out problems that need further study","PeriodicalId":232800,"journal":{"name":"2006 First International Symposium on Pervasive Computing and Applications","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128480626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Service-oriented computing (SOC) is considered as a new computing paradigm after the object-oriented computing paradigm. It utilizes services as fundamental elements for applications/solutions. Services are autonomous platform-independent computational elements that can be described, published, discovered, orchestrated and programmed using XML for the purpose of developing massively distributed interoperable applications. Web services technology is part of the SOC paradigm and can be considered as an implementation of the SOC model. Web services are featured with application, platform and provider independence. They provide an appropriate approach for building open large-scale application environments. In such environments, services are not treated as isolated and one-time affairs but rather as elements of an interactive, dynamic and collaborative architecture. Service collaboration within or across environments is modelled in terms of supported transactions or processes that are subject to norms or protocols specified for certain business domains. Services are thereby orchestrated vertically within one environment, or horizontally across multiple environments. As a result, an individual environment streamlines services in terms of internal transactions while restrains its function scope to be highly specific to the targeted user group. Multiple environments collaborate in order to extend their business chains. Web services have been supported by major IT vendors through their commercial platforms such as Microsoft's .NET and SUN's J2EE. Web services have had quick evolution and broad acceptance. However, there are still a number of issues that limit the wide applications of Web services in industry. Current Web services technologies lack semantic description, generic service model, dynamic composition, and flexible cooperation strategies. Software agents have been proved to handle sophisticated interaction patterns. Agent-orientation is an appropriate design paradigm to enable automatic and dynamic collaborations, especially for e-Business systems with complex and distributed transactions. In services realization, software agents are very essential for the provision of a focused and cohesive set of active capabilities. Therefore, we envision a combination of agent and Web services technologies and strongly believe that we are on the right track towards an evolution of current SOC paradigm. Software agents can be one of the essential evolvements of Web services in that they are functional entities, instead of simple interaction delegations or communication proxies. The idea is to exploit agents' capabilities of proactive interactions to enhance Web services' behaviours. With such a computing paradigm, software components, each representing both a service and an agent, cooperatively or competitively interact to provide unified services in a specified environment, such as brokering, pricing and negotiation in an e-marketpla","PeriodicalId":232800,"journal":{"name":"2006 First International Symposium on Pervasive Computing and Applications","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131512841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the requirement that a computing system should run continuously and persistently is never taken into account as an essential and/or general requirement by traditional system design and development methodologies. As a result, a traditional computing system often has to stop its running and service when it needs to be maintained, upgraded, or reconfigured, it has some trouble, or it is attacked. This is not desirable to any pervasive (ubiquitous) service. This paper intends to propose a systematic and methodological solution to the problem: to develop persistent computing systems with soft system bus technology to provide an infrastructure for various pervasive services.
