Fully-passive operation of the optical distribution network (ODN) is retained through reconfigurable optical add-drop multiplexers (ROADM) that are solely supplied by means of energy harvesting at the optical layer with a low feed level of -9 dBm. Deployment with a typical power consumption amounting to 90 fJ/bit guarantees an energy-conscious fronthaul technology.

The SUs bid for the various channels that the primaries want to sell; however their bids based on the preference for the channels. We use the signal to interference and noise ratio (SINR) as a metric for the preference; bids for channels with higher SINR are more than the ones that have low SINR. The proposed auction scheme allocates the channels such that the high-preference channels are allocated to the SUs- which does not necessarily maximize revenue for the PUs. The allocation of channels are done such that the i) SUs get their preferred channel, ii) channels are spatially re-used, and iii) a channel is not used by any interfering primary or secondary users. We use the interference conflict graph and the preference list as inputs to the auction-based allocation process. We validate the proposed allocation process through simulation experiments and show what fraction of secondary users get the channels and what the preference was for the assigned channel. Moreover, we measure the effect of the transmission range on the number of assigned channels. We also show that the proposed scheme is fair using Jain's fairness index.","PeriodicalId":416277,"journal":{"name":"2016 European Conference on Networks and Communications (EuCNC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128613674","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 evolution gives little to no attention to the specific needs of applications, beyond raw capacity. The ACINO concept is based on facilitating applications to explicitly specify requirements for requested services in terms of high-level (technology agnostic) requirements such as maximum latency or reliability. These requirements are described using intents and certain primitives which facilitate translation to technology specific configuration within the ACINO infrastructure. To support this application centric approach, SDN must have a key role in this evolution. There are representative use cases where SDN gives an added value when considering not only the network but also the application layer.","PeriodicalId":416277,"journal":{"name":"2016 European Conference on Networks and Communications (EuCNC)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114831917","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 ROF communication system is impaired with signal-dependent distortions in the optical fiber link such as shot noise and relative intensity noise. In this paper, these signal-dependent distortions of the ROF channel are analyzed in more details and a variance normalizing technique is proposed to normalize the noise power. In effect, the signal-dependent noisy ROF channel is converted to a signal-independent additive white Gaussian noise channel for which the conventional signaling techniques are efficient.

On the other hand, business case analysis of this new approach has yet to be analyzed. This paper discusses a forecast analysis of the application of MOTO solution within offloading market by investigating different business models and scenarios as well as value chains between new actors.

It has recently been shown that compressed sensing (CS) techniques can address the pilot contamination problem, however, the CS-based channel estimation requires prior knowledge of channel sparsity. To solve this problem, in this paper, an efficient channel estimation approach based on Bayesian compressed sensing (BCS) that based on prior knowledge of statistical information about the channel sparsity is therefore proposed for the uplink of multi-user massive MIMO systems. Simulation results show that the proposed method can reconstruct the original channel coefficient effectively when compared to conventional based channel estimation.","PeriodicalId":416277,"journal":{"name":"2016 European Conference on Networks and Communications (EuCNC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123963562","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}

To address this challenge a number of recent research efforts have focused on offloading media servers using P2P architectures, however they all fall under the assumption that the participating peers are in general cooperative. Ignoring security issues can significantly deteriorate the system's efficiency especially in real P2P systems where it is highly probable that at least one peer will have malicious behavior. The malicious peer can perform an attack to the system by polluting the video blocks that are exchanged, thus deteriorating the QoS. In this paper, we present a distributed P2P VoD system that is capable of identifying and isolating a malicious peer causing pollution. Its components that manage the overlay and the data scheduling are tested under diverse simulations that show promising results.","PeriodicalId":416277,"journal":{"name":"2016 European Conference on Networks and Communications (EuCNC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134417464","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}
