The description method is based on the predication logic and statechart. Predication is used to define concepts and statechart is used to describe the execution process of composite Web services. The exception handling policies are described formally according to how and when the exception handling actions are executed. ECA (event-condition-action) rules are used to express the events, conditions and exception handling actions during exception handling. An application case is presented to show how to describe the exception handling policies using our description method.","PeriodicalId":278518,"journal":{"name":"2007 IFIP International Conference on Network and Parallel Computing Workshops (NPC 2007)","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116603825","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}

Under a hostile military environment, sensor networks can be easily attacked by malicious nodes and hostile nodes using the natural cooperation of WSNs. In this paper, we introduce the trust mechanism in the human society into WSNs and propose a more overall trust model without a central trust authority, which provides a reliable approach to establish trust for WSNs. The approach combines all kinds of trust values together, including the direct trust and indirect trust value of nodes. The simulation results show that our trust model can efficiently defend against the attacks of the malicious nodes.","PeriodicalId":278518,"journal":{"name":"2007 IFIP International Conference on Network and Parallel Computing Workshops (NPC 2007)","volume":"64 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117037284","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, to deliver comparable overall run-time performance with C/C++, Java I/O must also keep up with that of C/C++. In this paper, we studied comprehensively the performances of Java communication stacks over InfiniBand and giga-bit Ethernet, and compared them with those of benchmarks written in C. We found the network performance of current version of Sun Java run-time could be parallel with C over giga-bit Ethernet. But for higher performance InfiniBand network, the current communication stacks, mainly the TCP/IP emulation layers, showed rather poor performances. It can be concluded it's necessary to invent new approach to support InfiniBand in Java applications.","PeriodicalId":278518,"journal":{"name":"2007 IFIP International Conference on Network and Parallel Computing Workshops (NPC 2007)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128549468","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}

This paper aims at finding a better solution to the global optimization problem of power consumption of the sensor network. First, this paper sums up the node scheduling scheme of minimum power consumption and no collision for wireless sensor network into the flexible scheduling problem. Then regard one data transmission at a certain moment as an antigen, and potential routes as antibody, and the power consumption by the node sequence as the fitness, respectively. Finally, the proposed algorithm eliminates the disabled nodes using the immune stabilization to reconstruct the network topology structure and builds the vaccine library by the secondary reaction of artificial immune. The simulation results show that the proposed algorithm can not only avoid the collision among sensor nodes when forwarding data packets, but also solve the global optimization problem of power consumption with fast convergence speed.","PeriodicalId":278518,"journal":{"name":"2007 IFIP International Conference on Network and Parallel Computing Workshops (NPC 2007)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128670026","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}

They are usually composed of components by invocation temporarily. Their components are often autonomic and execute independently. As to concurrency control, parallelism in there systems are more than in traditional distributed ones. So that serializability is too strict a correctness criterion to them. This paper divided transactions into atomic units according to semantic information. And interleaving between atomic units of different transactions is permitted to heighten parallelism. This newly proposed correctness criterion is named as weakly serializability. Weakly serializable schedule is non- serializable, but preserves data consistency at a higher level of semantics. Necessary and sufficient Condition of Weakly serializable schedule is presented and proved. Accordingly a distributed algorithm for concurrency control is given also.","PeriodicalId":278518,"journal":{"name":"2007 IFIP International Conference on Network and Parallel Computing Workshops (NPC 2007)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126687673","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}
