ROCH performance is evaluated on a $7$-node software-defined radio testbed using the open-source radio framework, GNU Radio, and Universal Software Radio Peripherals (USRP-N$210$s). The implementation of ROCH is facilitated by the architectural abstractions of the RcUBe radio framework, that provides real-time reconfigurability at the PHY, MAC, and network layers of the protocol stack.","PeriodicalId":62224,"journal":{"name":"世界中学生文摘","volume":"275 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73559152","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}

Denial-of-Service (DoS) attacks can make IdM operations unavailable, preventing the use of computational resources by legitimate users. This work presents SAMOS, a novel Scheme for DoS Attacks Mitigation by the reOrganization and optimization of the IdM System. SAMOS optimizes the reorganization of the IdM system components founded on optimization techniques, minimizing DoS effects and improving the system lifetime. Results considering data from a real IdM system indicate the scheme viability and benefits.","PeriodicalId":62224,"journal":{"name":"世界中学生文摘","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78440587","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, the infrastructure at venues that host live events provide poor, low-bandwidth connectivity. Instead of relying on infrastructure provided by the venue, we propose to stand up a temporary \"infrastructure\" using the very devices that need it, to enable content-sharing with nearby devices. To this end, we developed Krowd, a novel system that provides a key-value store abstraction to applications that share content among local, nearby users. We evaluated Krowd using over 200 hours of real-world traces from sold-out NBA and NHL playoffs and show that it is 50% faster and consumes 50% less bandwidth than alternative systems. We believe that Krowd is the only decentralized and distributed system to provide a key-value store made for neighboring mobile devices and of neighboring mobile devices.","PeriodicalId":62224,"journal":{"name":"世界中学生文摘","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88394761","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}

At the same time, these devices store personal, sensitive information, and there is a growing number of applications that leak it. We propose AntMonitor -- the first system of its kind that supports (i) collection of large-scale, semantic-rich network traffic in a way that respects users' privacy preferences and (ii) detection and prevention of leakage of private information in real time. The first property makes AntMonitor a powerful tool for network researchers who want to collect and analyze large-scale yet fine-grained mobile measurements. The second property can work as an incentive for using AntMonitor and contributing data for analysis. As a proof-of-concept, we have developed a prototype of AntMonitor, deployed it to monitor 9 users for 2 months, and collected and analyzed 20 GB of mobile data from 151 applications. Preliminary results show that fine-grained data collected from AntMonitor could enable application classification with higher accuracy than state-of-the-art approaches. In addition, we demonstrated that AntMonitor could help prevent several apps from leaking private information over unencrypted traffic, including phone numbers, emails, and device identifiers.","PeriodicalId":62224,"journal":{"name":"世界中学生文摘","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81920312","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}

WiDraw exploits the Angle-of-Arrival values of incomingWiFi signals at aWiFi device and enables hand trajectory tracking in both LOS and NLOS scenarios.
