Given the physical layer study results, we evaluate the applicability of the proposed scheme in real networking topologies and determine the number of end-users that can be served and the line rates they can enjoy for nine application scenarios in rural, semi-urban, urban and dense urban areas.

The cloud consists of dense massively air-interacting nodes, that provide a simple and uniform PHY interface to the clients. In this work we consider the Massive Interference (MI) scenario for the DIWINE network, where the number of cloud nodes is much larger than the necessity for a bare connectivity. To accommodate to the MI environment, we propose the interference neutralization (IN) scheme exploited at the cloud to eliminate the interference at the receiving nodes. A signaling protocol is also proposed to determine the transmitting and receiving nodes before data transmission. Numerical results show that the proposed IN with the signaling protocol can lead to good throughput and delay tradeoff under different traffic loads.","PeriodicalId":111472,"journal":{"name":"2014 IEEE 19th International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132672093","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 alleviate the huge infrastructure investment in the exponential growth of mobile traffic and improve local service flexibility, device-to-device (D2D) communications have been considered for the next generation mobile telecommunications. This has triggered investigation of fifth gernation (5G) to utilizes D2D communications for hetergenous networks. D2D communications enable users to transmit signals directly without going through the base station. However, many technical challenges need to be addressed for D2D communications to harvest the potential benefits. This requires learning how to improve the the model to better appeal to a wider base and move toward additional solutions. In this paper we provided a simple overview of D2D communications 5G hetergenous network by means of various Integer Linear programming. Finally, we present experiments on how Fractional knapsack using greedy algorithm can be used for power efficiency and improve throughput, thus allowing of future optimization problems.","PeriodicalId":111472,"journal":{"name":"2014 IEEE 19th International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114554667","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 opportunistic networks, these intermittent links are exploited, instead of mitigated, by temporal and/or spatial diversities in order to improve the network performance such as energy efficiency, delay, throughput and so on. Simulation is always an important method for the research in this challenged domain and a suitable simulator or simulation framework can greatly improve the research efficiency. The previous simulators or frameworks for opportunistic networks mainly focus on the design of upper layers but neglect the impact of physical layer on these layers. However, the reality of physical layer simulation is vital to the design of upper layers. In this paper, a simulation framework is developed using the MiXiM framework as basis which can simulate complex wireless physical environment. In this work, an integrated solution for simulation and analysis is provided including all communication layers and network performance analysis modules at each layer. This framework can help the researchers in this domain focus more on the design of protocols and less time on constructing a simulation tool.","PeriodicalId":111472,"journal":{"name":"2014 IEEE 19th International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114884407","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}

Detailed performance evaluation results are derived by means of simulations that confirm the successful transmission of both RF carriers with less than 2 dB power penalty over a long distance optical path.

R-SM is a multi-antenna wireless scheme that extends the concept of Spatial Modulation (SM) at the receiver side by using linear precoding. An accurate statistical framework is used for the characterization of the received signal. Using this framework, we provide novel and analytical bounds that characterize the ABEP of R-SM. Monte Carlo simulation results are used for the verification of the derived bounds. We compare R-SM against the corresponding standard Multiple-Input Multiple-Output (MIMO) scheme and show its performance. We conclude that R-SM is able to offer the same or better BER performance as traditional MIMO only when the spectral efficiency is low and the number of transmit and receive antennas is low.","PeriodicalId":111472,"journal":{"name":"2014 IEEE 19th International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117053108","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 do so, the source applies a fountain code and floods the encoded packets through the network, until they reach their destination or are lost in the process. We model the probability that the destination can recover the original transmissions from the received coded packets as a function of the network topology and of the number of redundant packets generated by the source, and show that our analytical results predict the outcome of simulations very well. These results are finally employed to discuss how the number of cooperating relays and the redundancy of the code should be set in order to achieve a good working point on the tradeoff between the reliability of end-to-end communications and the number of packet transmissions that take place in the network.","PeriodicalId":111472,"journal":{"name":"2014 IEEE 19th International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD)","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116205505","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 paper focuses on both the encoding and compression efficiency by measuring the PSNR values, SSIM scores and bit rate values of reference and non-reference signals. For the needs of the paper, the HEVC and AVC reference encoders have been used. Based on the experimental results, it is deduced that the HEVC meets its primary objective, which is to double the compression efficiency of the bit stream without significant degradation of the encoded video quality. Finally, interesting findings are also reported for the very low bit rate area of the encoding rate for low spatial resolutions.","PeriodicalId":111472,"journal":{"name":"2014 IEEE 19th International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD)","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132577844","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 network selection process starts by a network discovery operation which involves scanning the candidate networks in order to collect the required information for handover decision. Such operation consumes a considerable amount of energy at the terminal-end and yet the mobile terminal battery is limited. In this paper we propose a battery-aware scanning mechanism in which the number of scanned networks is dependent on the battery level at the terminal-end. Simulation results show an improvement of the terminal performance in terms of energy consumption and energy efficiency compared to the conventional approach where all the networks are scanned periodically.","PeriodicalId":111472,"journal":{"name":"2014 IEEE 19th International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124775580","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}
