Different than conventional packet-switching routing, our approach assigns the paths using a link utility based on sub-topologies of non-orthogonal frequencies. We use a graph coloring algorithm to calculate the utility of each link. We then propose two path assignment strategies: (i) single path, where each data stream traverse a unique path, and (ii) split-path, where the flows can be divided into multiple paths. Results show no best strategy fits all scenarios. Instead, in different situations, different algorithms are better suited.","PeriodicalId":135028,"journal":{"name":"2017 International Conference on Computing, Networking and Communications (ICNC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129372449","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}

LRCs have been recently proposed and used in practice in distributed storage systems such as Windows Azure Storage and Facebook HDFS-RAID. Theoretical bounds on the maximum locality of LRCs have been established, and optimal LRCs that achieve the obtained bound have been designed. Average locality of LRCs (r̅) is directly proportional to the costly repair bandwidth, disk I/O, and number of nodes involved in a repair process of a missing data block. There is a gap in the literature establishing the theoretical bounds on r̅. As an initial attempt to fill this gap, in this paper, we establish a lower bound on r̅ for the same code parameters used by Facebook HDFS-RAID. We also present a code that achieves the obtained bound. Comparing with the LRC used in Facebook HDFS-RAID, our proposed LRC improves the average locality by 22.5% without sacrificing the rate and minimum distance of the code.","PeriodicalId":135028,"journal":{"name":"2017 International Conference on Computing, Networking and Communications (ICNC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131168586","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 introduction of automated game theory to mission planning allows for a modular architecture and scalable approach across a range of platforms and facilitates rapid integration of new modes and technology. Game theory enhances a multi-objective management system, enabling it to intelligently coordinate and optimally achieve disparate mission objectives of a converged system. Our solution may also save money by offering a Pareto efficient process for mission plan validation, which reduces time needed to validate scenarios. An area of significant contribution in our work is our new genetic linear optimization, which is an innovative, developmental extension of our efforts comparing genetic algorithms with linear programming. We show results in receiver-operating characteristic (ROC) curves and compare the performance. We also quantify the performance improvement across all combinations of decisions or players in a linear program. We further enhance decision making by combining the best parts of multiple solutions. Our design provides insight into the most important or optimal weights for degrees of freedom and can be used to efficiently tune those weights. We also discuss tradeoffs for improving processing time with a sensitivity analysis.","PeriodicalId":135028,"journal":{"name":"2017 International Conference on Computing, Networking and Communications (ICNC)","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133565845","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}

Last recent years show that computers have evolved to handy devices which can be used nearly everywhere, not only at home. For this reason, location-based services which allow to associate peers in a network with geographical positions, e.g. to track a device in emergency cases, become interesting. In this paper, we introduce LobSter, a lightweight location-based service over unmodified DHTs like Chord [24], Kademlia [14] and Pastry [21] which supports the mobility of peers. Our evaluation compares LobSter to related work in stationary situations and gives insights about the general limits of distributed location-based services in mobile environments.","PeriodicalId":135028,"journal":{"name":"2017 International Conference on Computing, Networking and Communications (ICNC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127821451","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 presents a cloud bursting approach based on long- and short-term predictions of requests to a business-critical web system to determine the optimal resources of the system deployed over private and public data centers. In a private data center, a dedicated pool of virtual machines (VMs) is assigned to the web system on the basis of one-week predictions. Moreover, in both private and public data centers, VMs are activated on the basis of one-hour predictions. We formulated a problem that includes the total cost and response time constraints and conducted numerical simulations. The results indicate that our approach is tolerant of prediction errors. Even if the website receives bursty requests and one-hour predictions include a mean absolute percentage error (MAPE) of 0.2, the total cost decreases to a half the current cost while 95% of response time is kept below 0.15 s.","PeriodicalId":135028,"journal":{"name":"2017 International Conference on Computing, Networking and Communications (ICNC)","volume":"176 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114384361","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}

Traditional omni-directional antennas and directional antennas either generate significant interference or provide poor network connectivity. Reconfigurable antenna (RA) is an emerging antenna technology that can agilely switch among many different antenna states including radiation patterns, so as to suppress interference and maintain high connectivity at the same time. In this work, we systematically exploit the pattern diversity and fast reconfigurability of RAs to enhance the throughput of MWNs. We first propose a novel link-layer model that captures the dynamic relations between antenna pattern, link coverage and interference. Based on our model, a throughput optimization framework is proposed by jointly considering pattern selection and link scheduling. Our problem is formulated as a mixed integer non-linear programming problem. The superiority of reconfigurable antennas compared with traditional omni-directional and directional antennas is both theoretically proven, and validated through extensive simulations.","PeriodicalId":135028,"journal":{"name":"2017 International Conference on Computing, Networking and Communications (ICNC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114737157","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, sensor nodes have very limited communication ranges. Thus, relay nodes are required to ensure reliable connectivity throughout the WSN. On the other hand, relay nodes are typically more sophisticated and expensive than sensor nodes. Therefore, deployment strategies should seek to minimize the number of required relay nodes, a problem referred to as the Steiner Tree Problem with Minimum Number of Steiner Points (SMT-MSP), which has been shown to be NP-hard. This paper analyzes and improves the 3-star approximation algorithm by reducing the time complexity from O(n3) to O(nlogn) with the identical performance ratio.
