However, on the downside, torus suffers from its long network diameter. One way to address this problem is using random shortcuts. However, this approach does not consider the variety of data center traffic, and leads to severe non-uniform network performance. To address this problem, we propose the Flyover, which exploits the flexibility of optical circuit switching to add on-demand shortcuts, as a cost-efficient and scale-out network architecture for DCNs. The following three features guarantee Flyover a good performance. First, a new defined serpent flow instead of the elephant flow is prioritized. Unlike the elephant flow, which is big in size, the serpent flow is big in both size and distance. Through this, the electrical torus network could be maximally relieved and the overall network performance is optimized. Second, Flyover generates region-to-region instead of the point-to-point shortcuts. Therefore, the valuable optical shortcuts could be fully utilized. Third, a semi-random heuristic algorithm is proposed to achieve the advantages of both reducing computation time and improving network performance. Furthermore, several ways to expand Flyover are discussed and evaluated to make sure that Flyover is highly scalable. Finally, Flyover is extensively analyzed and compared with its counterparts using both simulations and prototypes. The results show that Flyover could maximally improve the network throughput by 135% and latency by 277%.","PeriodicalId":117136,"journal":{"name":"2015 24th International Conference on Computer Communication and Networks (ICCCN)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126907812","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, this potential is hindered by a gap between how individual mobile devices demand computational resources and how cloud providers offer them: offloading requests from a mobile device usually require a quick response, which may be infrequent, and is subject to variable network connectivity, whereas cloud resources incur relatively long setup times, are leased for long time quanta, and are indifferent to network connectivity. In this paper, we present the design of utility-based uploads sharing strategy in cloud scenarios, which bridges the above gap through providing computation offloading as a service to mobile devices. Our scheme efficiently manages cloud resources for offloading requests to improve offloading performances of mobile devices, as well as to reduce the monetary cost per request of the provider. We also schedule offloading requests to resolve the contention problem for cloud resources. The proposed scheme makes offloading decisions with a controlled risk to overcome the uncertainties caused by variable network connectivity and program execution. Simulation results show that the proposed scheme can reduce the costs of cloud resources and enable mobile computation speedup for mobile devices.","PeriodicalId":117136,"journal":{"name":"2015 24th International Conference on Computer Communication and Networks (ICCCN)","volume":"135 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120973325","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}

A network of secondary users (SUs) opportunistically accesses portions of the spectrum left unused by a network of licensed primary users (PUs). A central controller (CC) schedules the traffic of the SUs over the spectrum bands, based on distributed compressed spectrum sensing performed by the SUs. Both sensing and scheduling are controlled based on the current spectrum occupancy belief, with the goal to maximize the SU throughput, under constraints on the PU throughput degradation and the sensing-transmission cost incurred by the SUs. The high optimization complexity is reduced by proposing a partially myopic scheduling strategy, where the total traffic of the SUs is determined optimally via dynamic programming, whereas the allocation of the resulting total traffic across frequency bands is determined via a myopic maximization of the instantaneous trade-off between PU and SU throughputs, which can be solved efficiently using convex optimization tools. Structural results of the partially myopic scheduling strategy are proved. Simulation results demonstrate how the proposed framework allows to balance optimally the cost of acquisition of state information via distributed spectrum sensing and the cost of data transmission incurred by the SUs, while achieving the best trade-off between PU and SU throughput under the resource constraints available.","PeriodicalId":117136,"journal":{"name":"2015 24th International Conference on Computer Communication and Networks (ICCCN)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132335514","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}

Lossless data compression and decompression can be essential in increasing communication throughput, reducing communication latency, achieving energy-efficient communication, and making effective use of available storage. This paper experimentally evaluates several compression utilities and configurations on a modern smartphone. We characterize each utility in terms of its compression ratio, compression and decompression throughput, and energy efficiency for representative use cases. We find a wide variety of energy costs associated with data compression and decompression and provide practical guidelines for selecting the most energy efficient configurations for each use case. For data transfers over WLAN, the best configurations provide a 2.1-fold and 2.7-fold improvement in energy efficiency for compressed uploads and downloads, respectively, when compared to uncompressed data transfers. For data transfers over a mobile broadband network, the best configurations provide a 2.7-fold and 3-fold improvement in energy efficiency for compressed uploads and downloads, respectively.","PeriodicalId":117136,"journal":{"name":"2015 24th International Conference on Computer Communication and Networks (ICCCN)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115683184","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}

We have designed and implemented a programmable infrastructure called VNode on a Japanese testbed network. The VNode infrastructure allows the network developer or researcher to create a slice. A slice is a set of connected virtualized computational resources and link resources. The user can easily configure and modify own network topology and deploy service functions as software like SDN and NFV. We realize multicast streaming and adaptive bit rate streaming by deploying video processing functions in a slice. Moreover, we realize automatic function deployment that responds to traffic intensity. We conduct some experiments to confirm the feasibility and usability of our use cases and the VNode infrastructure. We establish data streaming via a slice with enhanced functionalities and measure the resource utilization rate. Furthermore, we conduct some experiments on a federated slice established between VNode and GENI, which is a programmable infrastructure in the U.S. The results show that we can enhance service functionalities and use resources more efficiently by deploying software functions on programmable infrastructures.","PeriodicalId":117136,"journal":{"name":"2015 24th International Conference on Computer Communication and Networks (ICCCN)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129644498","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}

In most applications, nodes act as data sources and forward information to a central base station (BS) that may also perform network management tasks. The critical role of the BS makes it a target for an adversary's attack. Even if an ad hoc network employs conventional security primitives such as encryption and authentication, an adversary can apply traffic analysis techniques to find the BS. Therefore, the BS should be kept anonymous to protect its identity, role, and location. Previous work has demonstrated distributed beamforming to be an effective technique to boost BS anonymity in wireless ad hoc networks; however, the increased anonymity and corresponding energy consumption depend on the quality and quantity of selected helper relays. In this paper we present a novel, distributed approach for determining a set of relays per hop that boosts BS anonymity using evidence theory analysis while minimizing energy consumption. The identified relay set is further prioritized using local wireless channel statistics. The simulation results demonstrate the effectiveness our approach.","PeriodicalId":117136,"journal":{"name":"2015 24th International Conference on Computer Communication and Networks (ICCCN)","volume":" 15","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132094550","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}
