However, it is difficult for conventional systems to meet the continuous and heterogeneous requirements from service providers and users simultaneously. This paper introduces an autonomous decentralized VoD system to provide service in heterogeneous quality with adaptability and fewer additional storage volume. In this system, service provider allocates layered streaming data in separated nodes distributed in different levels. The users send pull mobile agents to select appropriate nodes for required service quality. However, for changing preference of users and local congestion, the response time will become worse. To increase the capacity of the edge level with base layered data, Autonomous Data Reallocation Technology is proposed by dynamically reallocating the layered data between the nodes in different levels. Moreover, the tradeoff between Service Level Agreement (SLA) and response time is analyzed. The effectiveness of the proposed technology is proved by comparison with conventional system.","PeriodicalId":221833,"journal":{"name":"2011 Tenth International Symposium on Autonomous Decentralized Systems","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117046435","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}

In an indoor factory monitoring environment sensor relocation and/or addition are necessary with reorganization of production lines and/or starting of new production lines. Due to memory, processing, etc. constraints of the wireless nodes these addition and relocation affect the scalability of the network. In the dynamic topological changing environment decreasing sensor connection time and increasing number of connected sensors in the network are challenging problems for indoor wireless environment. A two-tier autonomous decentralized architecture has been proposed for the environment to solve the problem. The first layer consists of sensors and second layer consists of routers. In the architecture routers make community (a group of nodes mutually cooperate for a common goal is a community) to coordinate among local routers. This paper discusses about background coordination technology to switch sensor load of routers of a community to decrease sensor connection time. To achieve the timely online expansion of sensors the routers of the community share information. The simulation results show that the proposed background coordination technology can decrease sensor connection time and increase the number of connected sensors in the network.","PeriodicalId":221833,"journal":{"name":"2011 Tenth International Symposium on Autonomous Decentralized Systems","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116897982","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 specifications which are described in natural language are probably deficient and it is inadequate that the specifications are checked only based on the experience of experts. In this paper, a modelling method was applied on the description and the verification of the System Requirement Specification, SRS, of train control system. The Specification and Description Language, SDL, was used to describe the functional behavior of the onboard equipment which is defined in the SRS. First, we defined the principles of modelling which are summarized for the purpose of the interoperability validation. Then, we applied a top-down hierarchical approach to model the functional behavior. The model started from the system level to describe the interface and refined in the block level to show the interaction of system scenarios and detailed the state transition and the working processes of the system in the process level. Debugged the SDL model, we validated the model in Telelogic Tau tool to find the problems of the SRS. The results showed that the ambiguous terms and the incompatible descriptions of the SRS can be found. It can be helpful for the modification of the SRS and the quality of train control system further.","PeriodicalId":221833,"journal":{"name":"2011 Tenth International Symposium on Autonomous Decentralized Systems","volume":"352 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134194834","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}

Although a number of standards have been developed in this domain yet the realization is still a key challenge. Health Level 7 (HL7) is an information exchange standard which formulates specifications for interoperable communication. HL7 V3 uses Messaging Infrastructure (MI)for the communication but it cannot provide flexible communication environment. It is required to have end-to-end sessions and business scenarios from real healthcare environment. Service Oriented Architecture (SOA) provides a platform for system development and integration in order to achieve the main goal of interoperability along with flexibility. In HL7 V3, the communication between systems takes place using process artifacts (application roles, interactions, trigger events and information models). SOA based HL7 V3infrastructure consists of application roles as services that are responsible for the interaction between communicating entities. Our system provides services that have business perspectives in terms of capturing healthcare business workflows. The work in this paper is based on the HL7 V3specifications and also uses certain guidelines of Healthcare Service Specification Project (HSSP).","PeriodicalId":221833,"journal":{"name":"2011 Tenth International Symposium on Autonomous Decentralized Systems","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121986945","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}
