Recent research makes use of metaheuristic task scheduling techniques in addressing this concern. However, metaheuristic techniques are attributed with certain limitation such as premature convergence, global and local imbalance which causes insufficient task allocation across cloud virtual machines. Thus, resulting in inefficient QoS expectation. To address these concerns while meeting end-users QoS expectation, this paper puts forward a non-preemptive chaotic cat swarm optimization (NCCSO) scheme as an ideal solution. In the developed scheme, chaotic process is introduced to reduce entrapment at local optima and overcome premature convergence and Pareto dominant strategy is used to address optimality problem. The developed scheme is implemented in the CloudSim simulator tool and simulation results show the developed NCCSO scheme compared to the benchmarked schemes adopted in this paper can achieve 42.87%, 35.47% and 25.49% reduction in term of execution time, and also 38.62%, 35.32%, 25.56% in term of execution cost. Finally, we also unveiled that a statistical significance on 95% confidential interval has shown that our developed NCCSO scheme can provide a remarkable performance that can meet end-user QoS expectations.","PeriodicalId":273530,"journal":{"name":"International Journal of Advanced Computer Research","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131086496","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}

Nevertheless, the existing cloud virtualization systems are not secure enough regarding the mediocre degree \u0000of data protection, which avoids individuals and organizations to engage with this technology. Therefore, the security of sensitive data may be affected when mobile users move it out to the cloud exactly during the processing in virtual \u0000machines (VMs). Many studies show that sensitive data of legitimate users’ VMs may be the target of malicious users, which lead to violating VMs’ confidentiality and privacy. The current approaches offer various solutions for this security issue. However, they are suffering from many inconveniences such as unauthorized distributed VM access behavior and robust strategies that ensure strong protection of communication of sensitive data among distributed VMs. The purpose of this paper is to present a new security proxy-based approach that contains three policies based on secured hashed DiffieHellman keys for user access control and VM deployment and communication control management in order to defend against three well-known attacks on the mobile cloud environment (co-resident attacks, hypervisor attacks and distributed attacks). The related attacks lead to unauthorized access to sensitive data between different distributed mobile applications while using the cloud as a third party for sharing resources. The proposed approach is illustrated using a healthcare case study. Including the experimental results that show interesting high-efficiency protection and accurate attacks identification.","PeriodicalId":273530,"journal":{"name":"International Journal of Advanced Computer Research","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114253654","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}

It can be obtained from the assessment of the drug dose carefully and preciously. As a benefit of drug delivery automation, closed-loop method will present several advantages. It may prevent excessive dose amount or less needed dose and the controlled feedback system can decrease the cost of the healthcare by reducing the patient recovery period. This paper addresses the use of adaptive sliding mode controllers (ASMC) for calculating the depth of anesthesia by administrating a dose of propofol drug and measure patient state according to the monitoring device the bispectral index (BIS). In this study, we suggest a simple nonlinear control strategy consists of an ASMC combined with single neuron self-tune neural controller. It is used for maintaining DOA and reducing the effect of the nonlinear element. The adaptive controller uses the BIS value measured as a reference tracking value and propofol dose rate as a control signal. The parameters of the controller are tuned using a procedure based on the biogeography-based optimization (BBO) algorithm. The results indicate that including adaptive parts of the controller and tune its gains needed by BBO algorithm may enable optimal and stable performance for controller for all patients. It also provides fast reach to the induction phase and stay in a stable value in maintenance phase, which reflects the efficient response of the suggested controller if it compared to other nonlinear controllers. It is also justified by the results obtained that the suggested controller gives a very good response.","PeriodicalId":273530,"journal":{"name":"International Journal of Advanced Computer Research","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133156951","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}
