Nevertheless, a single cloud does not have limitless resources to offer to its users, hence the notion of an Inter-Cloud enviroment where a cloud can use the infrastructure resources of other clouds. However, there is no common framework in existence that allows the service owners to seamlessly provision even some basic services across multiple cloud service providers, albeit not due to any inherent incompatibility or proprietary nature of the foundation technologies on which these cloud platforms are built. In this paper we present a novel solution which aims to cover a gap in a subsection of this problem domain. Our solution offers a security architecture that enables service owners to provision a dynamic and service-oriented secure virtual private network on top of multiple cloud IaaS providers. It does this by leveraging the scalability, robustness and flexibility of peer-to-peer overlay techniques to eliminate the manual configuration, key management and peer churn problems encountered in setting up the secure communication channels dynamically, between different components of a typical service that is deployed on multiple clouds. We present the implementation details of our solution as well as experimental results carried out on two commercial clouds.","PeriodicalId":234594,"journal":{"name":"2012 18th IEEE International Conference on Networks (ICON)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132083487","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}

Meanwhile, new applications running over IPv6 networks will change the traditional traffic characteristics of IPv4 networks. In this paper, we present a measurement study on the traffic features and behaviors of the users over IPv4 and IPv6 in the campus network of XJTU. We shall investigate the differences between IPv4 and IPv6 traffic features in terms of the distribution of the average packet size, flow size, flow duration, and self-similarity of the packet size and traffic volume. As to the user's behaviors, we employ the connection degree to capture the behavior characteristics and Renyi entropy to measure behavior dynamics. The experimental results based on the traffic traces collected from the Northwest Regional Center of CERNET (China Education and Research Network) indicate that there exists distinct differences between IPv4 and IPv6 traffic due to the newly-emerged applications. The analysis results provide strategic guidance for traffic management and exhibit great potential in abnormal behavior detection in next generation network.","PeriodicalId":234594,"journal":{"name":"2012 18th IEEE International Conference on Networks (ICON)","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114416958","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}

This paper first compares these two kinds of uncertainties and comes to the conclusion that the environmental interference dominates the noise uncertainty problem. Aiming at alleviating the environmental interference, this paper proposed a power differentiation scheme to differentiate the target primary signal from the environmental interference produced by the simultaneously transmitted secondary signals and the device noise. The differentiated target primary signal power, rather than the total received composited power used in most conventional schemes, is used to construct the test statics for the energy detection to improve the sensing performance. The proposed power differentiation scheme does not require any prior knowledge of the primary signal except the geolocations of the primary transmitters and secondary users, thus, is a noncoherent scheme. Simulation results show that the proposed scheme can effectively cope with the environmental interference and can greatly improve the performance of energy detection-based spectrum sensing.","PeriodicalId":234594,"journal":{"name":"2012 18th IEEE International Conference on Networks (ICON)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123940880","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}

The development of WLAN technology is marked by the emergence of IEEE 802.11 standard family which are b, a, g, and n. The newest IEEE 802.11n standard is aimed at improving throughput especially in MAC layer by using frame aggregate mechanism utilizing the A-MSDU and A-MPDU schemes. On the other hand, the compressed Block ACK scheme, which is an extension of the Basic Block ACK scheme in IEEE 802.11e standard, was introduced. In this paper, we propose an analytical model to investigate the throughput performance which is produced by using A-MSDU scheme and Block ACK scheme. The throughput produced by the analytical model is then compared to the throughput produced by the A-MSDU and Block ACK scheme from the NS-3 network simulator. The mathematical simulation and NS-3 simulation results show the same outcome that demonstrates the accuracy of our proposed analytical model. The simulation result has also shown that the usage of A-MSDU and Block ACK scheme simultaneously can increase the throughput in MAC layer of IEEE 802.11n.","PeriodicalId":234594,"journal":{"name":"2012 18th IEEE International Conference on Networks (ICON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132578161","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}

However these integrated networks have different access technologies and complex designed parameters. Current researches on the uncertain relationship among those parameters in such a dynamic and complicated system made it difficult to optimize the global network performance. As their inter-dependencies of each parameter may have a nonlinear relationship on the system performance metric of interest. This paper proposes a novel approach to analyze the global optimization problem in a heterogeneous network. We adopt a non-additive model based on Choquet integral to deal with the observed data in order to determine the network parameters' significance. By adjusting the most significant parameter, we can optimize network transfer performance. A simulation platform, which is deployed two applications such as voice and video conferencing, has been developed using OPNET to support our approach. Experimental evaluation shows that the proposed method's feasibility and effectiveness.","PeriodicalId":234594,"journal":{"name":"2012 18th IEEE International Conference on Networks (ICON)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125328917","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}
