To adapt to such a new environment, software application systems must be more flexible, more reactive, and more evolvable than before [1]. Built upon services from autonomous external sources, these application systems also have to explicitly consider the trustworthiness of the services. With these considerations, this version of ARTEMIS middleware is featured by its support for (1) multiple coordination modes based on various software architecture styles; (2) dynamic software architecture-based online reconfigurations, in reaction to the runtime changes in the environment and requirements; (3) trustworthiness evaluation at both the service level and the system level, which helps users to ensure and improve user's satisfaction on the system constructed.","PeriodicalId":20631,"journal":{"name":"Proceedings of the 8th Asia-Pacific Symposium on Internetware","volume":"19 1","pages":"20"},"PeriodicalIF":0.0,"publicationDate":"2009-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85567120","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}

Due to the mobility and resource limit of devices in pervasive computing environments, the design and implementation of service composition will be a more complex and challenging task. In this paper, an approach based on behavioral modeling and analysis techniques for modeling service composition is proposed. A service behavior model is represented as Concurrent Regular Expressions and then is modeled as a Labelled Transition System by transforming Concurrent Regular Expressions into Finite State Process notation. Verification of the service behavior against specified system properties, (i.e. behavior consistency, safety) is becoming more flexible and effective.","PeriodicalId":20631,"journal":{"name":"Proceedings of the 8th Asia-Pacific Symposium on Internetware","volume":"1 1","pages":"19"},"PeriodicalIF":0.0,"publicationDate":"2009-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90172569","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}

A key issue in this framework is how these Internetware entities aggregate to form a coalition to fulfill the newly occurred requirements. This paper assumes that the Internetware entities distributed in Internet are autonomous and builds a mechanism for the aggregation of autonomous Internetware entities driven by requirements. A function ontology has been constructed for allowing the requirements to be understandable by these Interenetware entities so that these entities can recognize the requirements and realize that they are able to contribute for the realization of the requirements. After that, the requester and the contributors will negotiate to form an effective coalition.","PeriodicalId":20631,"journal":{"name":"Proceedings of the 8th Asia-Pacific Symposium on Internetware","volume":"26 1","pages":"18"},"PeriodicalIF":0.0,"publicationDate":"2009-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76885557","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}

The middleware collects and manipulates contexts from environments, providing context-aware applications well-defined interfaces to adapt their behaviors when environments change. However, some minor difference in the implementation of context-aware middleware may cause the same context-aware application behave differently. Such behavior deviation may lead to serious problems or even disasters for a context-aware application. It is thus desirable to check whether a mobile context-aware application behaves consistently before moving it from one middleware to another, or whether a context-aware application still works correctly when upgrading the underlying middleware? Existing approaches for context-aware applications are not adequate for detecting such behavior deviation because these approaches do not consider the impacts of the difference in the middleware implementation. In this paper, we study the strategies in the implementation of context-aware middleware and their impacts on the behavior of context-aware applications. By exploring the implied scenarios where a context-aware application may behave differently, new testing approach is proposed to detect the behavior deviation of a context-aware application running on different middleware by generating test cases to cover these implied scenarios.","PeriodicalId":20631,"journal":{"name":"Proceedings of the 8th Asia-Pacific Symposium on Internetware","volume":"90 1","pages":"4"},"PeriodicalIF":0.0,"publicationDate":"2009-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76335454","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}

Appropriate selection of high quality services used in from numerous candidates declaring similar functionalities is crucial to the overall quality of the composed system. As authority centers are not generally available in open environments, reputation-based mechanisms must be adopted to evaluate services. With more and more reputation systems proposed in the literature, there is an increasing need to evaluate and compare them objectively and systematically with a common controlled experiment of trust network environment. In this paper we propose a general simulation framework based on dynamic trust network for this purpose. Especially, the framework is capable to simulate the dynamic evolutions of the trust network, in addition to the static snapshots of the trust relationships. With this framework, some case studies are made to evaluate the effectiveness of several representative reputation mechanisms, and some interesting characters are revealed.","PeriodicalId":20631,"journal":{"name":"Proceedings of the 8th Asia-Pacific Symposium on Internetware","volume":"30 1","pages":"14"},"PeriodicalIF":0.0,"publicationDate":"2009-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85907079","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}

Previous research has addressed the quality-of-service (QoS) aware composition path selection problem. However, as the requests growing, the selected service composition path may violate the QoS requirements. In this case, more service replicas should be deployed on suitable nodes to improve the QoS. But which service component should be selected and where these service replicas should be deployed is a challenge. In this paper, we make a deep study on this service replication problem. We give a detailed description of service replication triggering time. And then, we propose LDCS (<u>L</u>ongest <u>D</u>elay Service <u>C</u>omponent <u>S</u>election) to select the bottle-neck service component by evaluating the real-time performance of all these components.
