The most fundamental part of virtualization is the hypervisor. To perform maintenance on a host server, we need to be able to move all of its VMs onto other host servers with minimum disruption to end users. Even more importantly, if our virtual workloads peak and need more resources, our virtual infrastructure should be able to automatically locate a host server with adequate resources and move the VMs to this host. And the entire process should be completely transparent to end users. VM migration, especially live migration is a desirable feature in Grid and Cloud Computing systems for load balancing, elastic scaling, fault tolerance, and hardware maintenance. The security and reliability issues that reside in VM live migration is a critical factor for its acceptance by IT industry. Though the performance is optimized through live migration, there are two important issues to be noted, reliability and security. In this paper, we propose how to migrate a VM Guest to another VM Host Server. We discuss the steps regarding the KVM live migration requirements and the security and reliability issues in live migration.","PeriodicalId":403612,"journal":{"name":"2011 International Conference on Process Automation, Control and Computing","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115122529","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}

An alternate method is used that is called fuzzy controller. In this paper, a fuzzy controller has been introduced.

Also, a well known problem of orthogonal frequency division multiplexing (OFDM) i.e the occurrence of high peak- to-average power ratio (PAPR) in the time domain signal reduces the efficiency of transmit high power amplifier.In this paper, we propose a closed loop orthogonal frequency division multiplexing multiple- input multiple-output (MIMO) transmit preprocessing system, where the channel coding method referred as pilot symbol assisted rateless coding (PSAR) is used to mitigate the effects of fading and three PAPR reduction methods are used and the best method to reduce PAPR is chosen. The performance of proposed system is measured in terms of bit error rate (BER) and complementary cumulative distribution function (CCDF) for PAPR. The proposed system achieves about 3 dB improvement in PAPR over the traditional OFDM.","PeriodicalId":403612,"journal":{"name":"2011 International Conference on Process Automation, Control and Computing","volume":"504 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116202042","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 this paper modified wireless token network (MWTN) is proposed to provide the required QoS by decreasing the size of the contention window (CW).

We are describing the OpenViBE platform that serves all the necessary steps required in designing typical BCI system. OpenViBE works on EEG signals to measure brain activity. EEG signals on the basis of frequencies and amplitudes are classified into different bands corresponding to different states like sleep, awake, mediation and alert.

This paper employs a new approach to regulate the blood glucose level of type I diabetic patient under an intensive insulin treatment. The closed-loop control scheme incorporates the design of robust H¿¿ controller to maintain the normoglycemic average of 80 mg/dl. Due to cost and complexity involved in testing the control algorithms to real patients, studies are done using a Type I diabetic patient model. Controller performance is assessed in terms of its ability to reject the effect of meal disturbance and to overcome the variability in the glucose-insulin dynamics from patient to patient. Computer simulations are used to evaluate the effectiveness of the proposed technique and to show its superiority in controlling hyperglycemia over other existing algorithms.","PeriodicalId":403612,"journal":{"name":"2011 International Conference on Process Automation, Control and Computing","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125942603","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 is a major concern as a grid enables sharing of valuable resources and sensitive information across heterogeneous users. Authentication, message integrity and confidentiality are the major concerns in grid security. The proposed approach uses a trigon based authentication and authorization of the grid entities. Grid service is stateful and transient web service, which can be invoked by clients, and is considered to be the mainstream of future internet. A service is defined by identifying sequences of specific message exchanges that cause the service to perform some operation. By thus defining these operations only in terms of message exchange, we achieve great flexibility in how services are implemented and where they may be located.The creation of Web Services standards is an industry-led initiative, with some of the emerging standards in various states of progress through the World Wide Web Consortium (W3C). The security protocol has been implemented and tested using Globus middleware. To achieve reuse of behaviors of this authentication concept, operations are often grouped together to form a SHA based authentication service using prerequisites as build.xml , globus-build-service.sh, WSDL file and globus as middleware.","PeriodicalId":403612,"journal":{"name":"2011 International Conference on Process Automation, Control and Computing","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128483005","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}
