The architecture defines management planes and software components that provide the mechanisms for collecting monitoring data, predicting possible future values of the network metrics and resources usage, and applying management decisions to keep the provision optimal. The proposed research approach is based on novel time series and epidemic spread models, and the outcome is used for the optimal distribution of streaming data, among Content Delivery Networks, cloud-based providers and Home Media Gateways. The proposed epidemic diseases model adopts the characteristics of the multimedia content delivery over the network architecture. In this context, the paper aims to present the advantages of using such models, by presenting and analyzing an epidemic spread scheme for Video on Demand (VoD) delivery, to predict future epidemic spread behavior. The validity of the proposed system is verified through several sets of extended experimental simulation tests, carried out under controlled simulation conditions.","PeriodicalId":370856,"journal":{"name":"2015 IEEE 20th International Workshop on Computer Aided Modelling and Design of Communication Links and Networks (CAMAD)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129610906","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}

With DF-JD, only if the relay's received information sequence can be decoded with an arbitrarily low error probability, it is forwarded to the destination. On the contrary, with LF, the relay node always forwards decoded information sequence to the destination even if a decoding error is detected. Interleaving is used at relay and joint decoding is utilized at the destination to exploit the source-relay correlation for both techniques. The outage probability of conventional DF system with maximum ratio combining (DF-MRC) performed at the destination is also presented. Asymmetric statistical properties of the fading variations for each link are taken into account. It is shown that regardless of the presence of line-of-sight component, the outage probability with LF relay system is significantly smaller than that with DF-JD and DF-MRC relay systems. The impact of the per-link spectrum efficiency, representing the modulation multiplicity and channel coding rate, on outage probability is also investigated. It is found that, given that the specified per-link spectrum efficiency is satisfied, LF relay system always achieves lower outage performance than that with DF-JD and DF-MRC systems. The accuracy of the analytical results are verified by a series of Monte Carlo simulations.","PeriodicalId":370856,"journal":{"name":"2015 IEEE 20th International Workshop on Computer Aided Modelling and Design of Communication Links and Networks (CAMAD)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128593271","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 non-beacon-enabled mode is simpler and does not require time synchronisation; however, it lacks an explicit energy saving mechanism that is crucial for its deployment on energy-constrained sensors. This paper proposes a distributed sleep mechanism for non-beacon-enabled IEEE 802.15.4 networks which provides energy savings to energy-limited nodes. The proposed mechanism introduces a sleep state that follows each successful packet transmission. Besides energy savings, the mechanism produces a traffic shaping effect that reduces the overall contention in the network, effectively improving packet delivery ratio. Based on traffic arrival rate and the level of network contention, a node can adjust its sleep period to achieve the highest packet delivery ratio. Performance results obtained by ns3 simulations validate these improvements as compared to the IEEE 802.15.4 standard.","PeriodicalId":370856,"journal":{"name":"2015 IEEE 20th International Workshop on Computer Aided Modelling and Design of Communication Links and Networks (CAMAD)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132216838","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}

Moreover, it has been estimated that IBFD-equipped wireless networks can be more energy-efficient than half duplex ones due to the reduced energy cost of packet collisions. However, one key challenge for implementing an energy-efficient IBFD system is the cancellation of the interference produced by the transmitted signal. In fact, existing self-interference cancellation (SIC) techniques are not always energy-efficient, as the effect of the interference reduction might not be able to compensate the additional electronic power consumption introduced by the SIC module. Following this rationale, in this paper we propose and energy-efficient IBFD architecture that adapts the SIC module to the link conditions. By studying a symmetric bi-directional full duplex link, we show that the proposed architecture obtains significant energy savings by using a simple SIC scheme for short-range transmissions. More powerful SIC techniques are shown to be an energy-optimal choice only when transmitting over long link distances.","PeriodicalId":370856,"journal":{"name":"2015 IEEE 20th International Workshop on Computer Aided Modelling and Design of Communication Links and Networks (CAMAD)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130032277","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}
