We describe the details of our prototype policy defined networking solution that automatically translates high-level policies into device level implementations. We develop a novel metagraph model that can be used for policy specification, verification and refinement. We show that sophisticated traffic engineering policies can be implemented automatically on commodity hardware using our framework.","PeriodicalId":317649,"journal":{"name":"2016 26th International Telecommunication Networks and Applications Conference (ITNAC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124288091","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}

Most prior works mainly focus on proposing an efficient algorithm that yields good performances, and evaluate their solutions on a certain network model, particularly in cases when every user can connect to all the available base stations (BSs). In this paper, we evaluate the impact of different aspects of network models, including (i) network topology and (ii) bandwidth allocation, on the performance of RAT selection algorithms to fully understand their limitations. Using simulations on realistic network models, this paper evaluates how different network parameters such as link density, user density or bandwidth distribution can lead to significant differences in algorithm performance. The paper demonstrates that among all the parameters, the performance of adaptive RAT selection algorithms are most significantly effected by the number of base stations that a user can connect to.","PeriodicalId":317649,"journal":{"name":"2016 26th International Telecommunication Networks and Applications Conference (ITNAC)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125238098","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 performance of these systems can be depended on many factors including response time or latency between them and the ability to interconnect between devices. In this paper, a Peer-to-peer (P2P) overlay network is discussed that can be used for real-time end-to-end remote instrumentation for IoT applications. P2P overlay networks are used for various purposes from content distribution through to media sharing. But in contrast to traditional P2P systems, IoT systems can be highly sensitive to network latency. The main contribution of this paper is a distributed algorithm to create the overlay network that assigns peer nodes to super-peer nodes in the network containing large numbers of smart devices with the aim of minimizing system wide network latency. Other constraints regarding the nodes ability to become a super-peer node such as connectivity and limited processing capacities of the smart devices are also considered in context of a P2P remote instrumentation system. The algorithm has been validated through simulation.","PeriodicalId":317649,"journal":{"name":"2016 26th International Telecommunication Networks and Applications Conference (ITNAC)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122449463","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}

While this approach has great potential to serve as an experimental platform, in particular for Software Defined Wireless Networks, it has not been extensively evaluated in terms of experiment result accuracy and fidelity. This is critical for any system that integrates simulation with real-time components. In this paper, we present a detailed evaluation of the fidelity of experimental results of Mininet-ns3-WiFi.

Once their user clients enter into WiFi AP coverage, they will be handed over to WiFi AP from BS in order to offload mobile data traffic. However, if there are too many BS user clients enter into WiFi AP coverage, it may lead to excessive handover to WiFi AP and thus reduce the data rate even slower than that of BS. On the other hand, Software Defined Network (SDN) is a promising technic to efficiently manage various kinds of networks. This paper proposes a FMSDN (Flow Management on Mobile Data Using SDN) mechanism, which uses SDN technology to manage the handover among WiFi AP and 3G/4G base stations. The design philosophy is that the SDN controller is responsible for making handover decision according to whichever access network (WiFi or 3G/4G) is able to offer higher service data rate to clients. Simulation results show that compared to Enforced Handover and Horizontal Handover methods, FMSDN is proved to be able to enhance service data rate with QoS guaranteed.","PeriodicalId":317649,"journal":{"name":"2016 26th International Telecommunication Networks and Applications Conference (ITNAC)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126500344","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}

Signature matching is the most time critical operation in content aware networking. Improving broadband speed necessitates the need for hardware acceleration of signature matching to manage and safeguard all the Internet of Things (IOT) clients connected to the smart home. Deterministic Finite Automata (DFA) allows the signature matching operation to be performed in linear time but has an exponential storage complexity. Bitmap based transition compression techniques are hardware friendly and can be used to achieve signature matching at multi gigabit throughput. However, its drawback is inefficient transition compression which results in storage of redundant transitions after the compression. We propose two bit masking techniques to efficiently compress transitions over existing bitmap based techniques. Compression ratios of 98% can be achieved using the proposed techniques, which in turn results in a 50% reduction of memory usage to store the compressed automata. A hardware acceleration architecture is proposed for each technique to decompress the transitions to achieve signature matching at multi gigabit rates.","PeriodicalId":317649,"journal":{"name":"2016 26th International Telecommunication Networks and Applications Conference (ITNAC)","volume":"2019 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116753324","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 superior performance of coset codes constructed from well-rounded lattices has been illustrated in several simulations. In the present article, this work is extended to fading multiple-input multiple-output (MIMO) wiretap channels, and similar design criteria as in the SISO case are derived. Further, explicit coset codes for Rayleigh fading MIMO wiretap channels are designed.
