In this paper, we present a novel clustering algorithm for high density IEEE 802.15.4-2015 Time-Slotted Channel Hopping (TSCH). In particular, the proposed methodology merges a variety of solutions into an integrated clustering design. Assuming an homogeneous network distribution, the proposed configuration deploys a hierarchical down-top approach of equally numbered sub-groups, in which the formation of the separate sub-groups is adapted to the network density and the node selection metric is based on the link quality indicator. The presented algorithm is implemented in Contiki Operating System (OS) and several test vectors have been designed in order to evaluate the performance of the proposed algorithm in a COOJA simulation environment. Performance results demonstrate the capability of the clustering structure since compared to the default scheme it significantly improves the energy efficiency up to 35%, packet drops more than 40% as well the packet retransmission rate. Last but not least, the outcome of this study indicates a major increase in the network lifetime, i.e., up to 50%.","PeriodicalId":106141,"journal":{"name":"2017 IEEE Symposium on Computers and Communications (ISCC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133679422","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}

SDN offers a number of advantages as the existing resources can be virtualized and orchestrated to provide new services to the end users. Such a technology should be accompanied by powerful mechanisms that ensure the end-to-end quality of service at high levels, thus, enabling support for complex applications that satisfy end users needs. In this paper, we propose an intelligent mechanism that agglomerates the benefits of SDNs with real-time “Big Data” forecasting analytics. The proposed mechanism, as part of the SDN controller, supports predictive intelligence by monitoring a set of network performance parameters, forecasting their future values, and deriving indications on potential service quality violations. By treating the performance measurements as time-series, our mechanism employs a novel ensemble forecasting methodology to estimate their future values. Such predictions are fed to a Type-2 Fuzzy Logic system to deliver, in real-time, decisions related to service quality violations. Such decisions proactively assist the SDN controller for providing the best possible orchestration of the virtualized resources. We evaluate the proposed mechanism w.r.t. precision and recall metrics over synthetic data.","PeriodicalId":106141,"journal":{"name":"2017 IEEE Symposium on Computers and Communications (ISCC)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123519487","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, SDN expands the attack surface of the communication infrastructure, thus necessitating the introduction of additional security mechanisms. A wind park is a good example of an industrial application relying on a network with strict performance, security, and reliability requirements, and was chosen as a representative example of industrial systems. This work highlights the benefit of leveraging the flexibility of SDN/NFV-enabled networks to deploy enhanced, reactive security mechanisms for the protection of the industrial network, via the use of Service Function Chaining. Moreover, a proof of concept implementation of the reactive security framework for an industrial-grade wind park network is presented. The framework is equipped with SDN and Supervisory Control and Data Acquisition (SCADA) honeypots, modelled on (and deployable to) an actual, operating wind park, allowing continuous monitoring of the industrial network and detailed analysis of potential attacks, thus isolating attackers and enabling the assessment of their level of sophistication.","PeriodicalId":106141,"journal":{"name":"2017 IEEE Symposium on Computers and Communications (ISCC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126527765","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}

Regulatory concerns, e.g., about content-specific charging, constrain the ISPs' search for new revenue sources. This paper analyzes a revenue model where an access ISP acts as a publisher of ads to users who explicitly opt for an ad-sponsored access plan of the ISP. First, we conduct a survey showing a substantial interest of users in ad-sponsored Internet access. Then, we mathematically characterize the advertising revenue model and asses its economic feasibility based on real data from two access ISPs and an ad publisher. While the ad revenues are tangible, they do not completely cover the costs of the access ISPs. Even in relative terms, a larger access ISP benefits more from the advertising, with the ad revenues covering up to 50% of the ISP's capital expenditure. Complementing the subscription fees, the access ISPs can leverage the ad revenues to meaningfully incentivize the users with better Internet connectivity, such as 6–9 Mbps in extra data rates or 12–20 GB in extra data caps for the two considered ISPs.","PeriodicalId":106141,"journal":{"name":"2017 IEEE Symposium on Computers and Communications (ISCC)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114947669","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}

HL7's focus has recently been extended to regional healthcare cloud infrastructures but not yet reached the lightweight fog infrastructures emerging from niche healthcare areas such as body area networks (BANs) and the massive flow of personal medical records resulting from off-the-shelf e-health devices and networks. This paper addresses the issue of interoperability between fog and cloud computing platforms by i) proposing a framework for a standardized exchange of information between healthcare entities ii) designing and implementing a software tool to be integrated into medical data dissemination protocols to ensure interoperability and iii) evaluating the impact of the software tool on the transport of data when exchanging healthcare information using “in-band” and “out-band” transport over the IEEE802.15.4/ZigBee and WiFi protocols. Our results reveal that, for the lightweight devices used by fog infrastructures, “out-band” transport over WiFi with edge data translation into HL7 records is a better option than “in-band” transport.","PeriodicalId":106141,"journal":{"name":"2017 IEEE Symposium on Computers and Communications (ISCC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117045812","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}

Despite the stringent performance requirements for such applications, the IEEE 802.11p standard still uses the carrier sensing medium access/collision avoidance (CSMA/CA) protocol. The latter when used in broadcast fashion employs a randomly selected backoff period from a fixed contention window (CW) range, which can cause performance degradation as a result of vehicular density changes. Concerns regarding the robustness and adaptiveness of protocols to support time-critical applications have been raised, which motivate this work. This paper investigates how the maximum CW size can be optimised to enhance performance based on vehicular density. A stochastic model is developed to obtain the optimal maximum CW that can be integrated in an amended CSMA/CA protocol to maximise the single-hop throughput among adjacent vehicles. Simulations confirm our optimised protocol can greatly improve the channel throughput and transmission delay performance, when compared to the standardised CSMA/CA, to support safety application in VANETs.","PeriodicalId":106141,"journal":{"name":"2017 IEEE Symposium on Computers and Communications (ISCC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124049231","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}
