The OMG defined CORBA Event Service for asynchronous messaging, which provides a flexible channel for asynchronous communication among the distributed and collocated objects. In the existing Event Service channels are created manually by the developers or users to process and disseminate the events. Also, the channel management is static which may cause bottleneck in some channels. In this paper, thus, we propose a dynamic context-based channel management scheme by efficiently combining name service with event service. It is embedded in the CALM(Component- based Autonomic Layered Middleware) developed by us, which has been implemented based on ORB. Computer simulation reveals that the proposed approach significantly reduces the event delivery and processing time of the existing omni Event Service and TIBCO.","PeriodicalId":386960,"journal":{"name":"2007 International Conference on Computational Science and its Applications (ICCSA 2007)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134230246","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}

Subjects are supposed to perform the primary task (typing task watching the main monitor) and the secondary task (clicking targets with the mouse, which appear randomly in the sub-monitor) at the same time. The secondary tasks were differentiated with three different task intensities. During the experiment, the primary and secondary tasks were measured and evaluated depending on the intensities of the subtasks and the locations of the sub-monitors. Followings are the conclusions which were obtained after the evaluation: 1) The higher the task intensity is, the lower the task performance. 2) Regardless of the task intensity, the task performance of the subtask is high in the center of the monitor. When the task intensity is low, the center section of the monitor becomes the starting point for searching. 3) When the task intensity is high, the task performance in the left section of the monitor becomes low.","PeriodicalId":386960,"journal":{"name":"2007 International Conference on Computational Science and its Applications (ICCSA 2007)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116536752","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}

Security countermeasures are implemented to prevent threat agents from successfully achieving these goals. Because the general systems of today are composed of a number of components such as servers and clients, protocols, services, and so on, the possibility of success of attack may be increased. As though Systems connected to network have become more complex and wide, unfortunately, the researches for the systems are focused on the 'performance' or 'efficiency'. While most of the attention in system security has been focused on encryption technology and protocols for securing the data transaction, it is critical to note that a weakness (or security hole) in any one of the components may comprise whole system. Security engineering is needed for reducing security holes may be included in the Information systems. This paper proposes a method for securing the Information systems by evaluation of security functions of system component. This paper proposes Information system security evaluation and certification for achieving some level of assurance each owners of their Information systems want to get.","PeriodicalId":386960,"journal":{"name":"2007 International Conference on Computational Science and its Applications (ICCSA 2007)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124156908","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}

To provide the right responses quickly for the diverse events, wireless sensor nodes have cooperation with together. For successful cooperation, the time synchronization among sensor nodes is an important requirement for application execution. In wireless sensor networks, message packets are used for the time synchronization. However, the transmission of message packets dissipates the battery energy of wireless sensor nodes. Since wireless sensor nodes works on the limited battery capacity, the excessive use of message packets has a negative impact upon their lifetime. In this paper, reference interpolation protocol is proposed for reducing the number of message packets for the time synchronization. The proposed method performs time interpolation between the time of reference packets and the global time of the base station. The proposed method completes the synchronization operation with only two message packets. Due to the simple synchronization procedure, our method greatly reduces the number of synchronization messages. From the decrease in the transmission of message packets, the convergence time among wireless sensor nodes is shortened and the lifetime of wireless sensor nodes is also prolonged as much as the amount of saved battery energy.","PeriodicalId":386960,"journal":{"name":"2007 International Conference on Computational Science and its Applications (ICCSA 2007)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130041693","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}
