For example in data center, networks are typically consists of access and aggregation L2 switches and core L2/L3 switches networks. However, new trends for server virtualization can change traffic dynamics, i.e. virtualized host can be located at any locations in the network and connections among servers are set up independently from physical network structure. Therefore static network structure cannot stay optimal and thus, we propose a network architecture whose structure is logically defined and flexibly reconfigurable. The network uniformly consists of OpenFlow switches and constructs a logical routing hierarchy defined by the software at OpenFlow controller. We evaluated our scheme to construct an efficient data center core network. We discussed types of logical structures and path selection algorithms with the constraint of flow table usage, which is one of the most critical constraints for scalable OpenFlow networks. Our simulation evaluation indicates that (1) full-mesh, hypercube and ring-based networks are the realistic logical structure design and that (2) hyperbolic path selection scheme has doubled the path capacity.","PeriodicalId":145328,"journal":{"name":"2009 International Conference on Intelligent Networking and Collaborative Systems","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121468311","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}

As the use of the Grid is extending, a numerous set of distributed resource allocation frameworks have been developed to attain efficient resource management while keeping the scalability of the Grid. However, those frameworks make use of either simple double auction mechanisms or complex approximations to the NP-complete problem of the combinatorial auction. The problem of those mechanisms is that of its generality, that is, they have not been specially designed for the trading of time-leased computational resources. In this paper we present a novel variant of the double auction that has been specially adapted to trade time-differentiated resources as Grid resources can be considered. The paper presents the data structures, algorithms and architecture of the economic mechanism as well as it presents the evaluation of the mechanism through simulation. Simulated results are compared with the main double auction implementations found in the literature. The paper constitutes an approach to improve efficiency of resource allocation in the Grid from the point of view of the economic model and not from architectural aspects addressed by most of the contributions found in the literature.","PeriodicalId":145328,"journal":{"name":"2009 International Conference on Intelligent Networking and Collaborative Systems","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124857920","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 have a very wide range of applications such as environment monitoring and military applications like battlefield monitoring. Sensors and their data are vulnerable to various attacks, like data injection, deletion, modification or even node replacement. Because of the resource limitation, security mechanisms that are based on traditional security techniques like public key cryptography and digital signatures are too heavy for wireless sensor networks. Watermarking is considered an attractive alternative because of its light resource requirements. This paper proposes a new technique for providing data integrity for wireless sensor network. The proposed scheme is based on distortion free watermarking. Most of the prior works embed the watermark by replacing the least significant bits of the data. While some applications can tolerate small errors in the data readings, other applications are sensitive to errors. The proposed watermarking technique embeds the watermark in the order of the data elements, and thus, does not cause distortion to the data items. We provide a detailed security analysis to show the robustness of the proposed techniques against various types of attacks. The proposed technique is implemented and the performance, in terms of the attack detection rate and the ability to identify the victim element is evaluated. In case of single attack the proposed technique can identify the victim data reading with high probability (up to 95%). The cost in terms of the execution time of the watermark calculation and embedding is also measured.","PeriodicalId":145328,"journal":{"name":"2009 International Conference on Intelligent Networking and Collaborative Systems","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131944942","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}
