Nevertheless, the study on network coding in convergecast is still in the theoretical analysis and the simulation stage. In order to investigate the network coding gain of convergecast in realistic wireless sensor networks, a network coding-based convergecast scheme is realized in this paper. The experiment is conducted in the basic size of convergecast whose size is limited below four, which is for the purpose of eliminating as much interference from the large size of convergecast network as possible. Performed in traditional convergecast scheme and network coding convergecast scheme, the experiment on collection rate and energy consumption are evaluated under different link delivery ratios and scales of convergecast network. The experiment results show that network coding is certain to introduce benefit in the case of poor link equality. However, it is inferior to the traditional scheme when the wireless link delivery ratio is high enough due to the conscious overhearing and the prerequisite of successful decoding.","PeriodicalId":255477,"journal":{"name":"Proceedings of 2014 International Conference on Cloud Computing and Internet of Things","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116912284","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 adjusts data acquisition rates according to the congestion level in a distributed manner, thereby alleviating and avoiding congestion as much as possible. It also makes its best effort to deliver information of high priorities in a timely manner and ensure uninterrupted sensing. Our experiments demonstrate that the scheme offers a much higher delivery rate of the high-priority data compared with the original scheme when the network undergoes different levels of congestion.","PeriodicalId":255477,"journal":{"name":"Proceedings of 2014 International Conference on Cloud Computing and Internet of Things","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114484649","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}

Though many applications need only secret keys, FHE has not been achieved properly through symmetric cryptography. Major hurdle is the need to refresh noisy ciphertexts which essentially requires public key and bootstrapping. We introduce a refreshing procedure to make a somewhat homomorphic scheme, fully homomorphic without requiring bootstrapping. Our scheme uses symmetric keys and has performance superior to existing public-key schemes.","PeriodicalId":255477,"journal":{"name":"Proceedings of 2014 International Conference on Cloud Computing and Internet of Things","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132181225","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}

Using virtualization technology, a single physical machine can provide multiple isolated virtual machine for users, which will improve the overall system resources usage.

To solve NUMA problem, many solutions have been proposed to reduce its performance impact on virtual machines and improve the overall system performance.

Those solutions have welldefined functions for integrating with enterprise environment. However, not all enterprises have enough resource to deploy, maintain and manage their own services. On the other hand, application service providers are searching for efficient and automatic service based on these storage solutions for more profits. In this paper, we propose a hosted private storage architecture based on COSA (Cloud Object Storage Appliance) and CAKE (Cloud Application Kernel Environment). In this architecture, each appliance hosted in a data center with Internet connectivity, storage pool and hypervisor(s); and a portal machine can provide self-service and monitoring features to enterprise and application service provider.

In the virtualized system, the scheduler plays an important role in effecting the performance of whole system. Traditional scheduler that focus on the fairness of VMs would cause problems in I/O performance and latency. In order to eliminate the I/O latency issue, we propose a virtual machine scheduling model based on multiprocessor system. We also implement a prototype in Xen 4.3.0 and evaluate it with several benchmarks. Experiment results demonstrate that our scheduling model can improve the I/O performance effectively. The bandwidth of disk increase by 53.6% and that of network increase by 39.4%. Meanwhile, our method does not change the scheduling algorithm of CPU-intensive VM so that the scheduling fairness is ensured.","PeriodicalId":255477,"journal":{"name":"Proceedings of 2014 International Conference on Cloud Computing and Internet of Things","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123772681","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}
