An open loop analysis of a photovoltaic chain, modeled in matlab-simulink, allows to extract the maximum power of the photovoltaic panel. The principle is based on the determination instantaneously of the conductance and its tendency materialized by a signed increment. A buck step down converter is used to adapt the voltage to its appropriate value to reach a maximal power extraction. This novel analysis method applied to the photovoltaic system is made under different atmospheric parameters. The performances are shown using Matlab/Simulink software.","PeriodicalId":345854,"journal":{"name":"2016 5th International Conference on Multimedia Computing and Systems (ICMCS)","volume":"672 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134126839","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}

Many mechanisms have been trialed, among which the Diffie-Hellman (DH). Though DH has been effective to some extent, flaws have been detected and even alternatives have been proposed. It is within this framework that a new model has been designed-the S-WANE model. Various researches have validated this model. In the present work, we carry out a comparative study between DH and S-WANE. To that end, we studied the two mechanisms. Analytical and experimental validations have shown the advantages of S-WANE over DH. Its advantages could be assessed in terms of robustness to some attacks such as “The-Man-in-the Middle”. Thus, we have proposed S-WANE as an alternative to replace DH everywhere the latter is used.","PeriodicalId":345854,"journal":{"name":"2016 5th International Conference on Multimedia Computing and Systems (ICMCS)","volume":"223 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116032883","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, the high load variability of such MMOG services makes hard to satisfy a good QoE. This paper aims to contribute to this effort, by proposing a proactive dynamic provisioning approach which predicts future workload of an MMOG service and allocates in accordance the sufficient amount of resources. Based on real MMOG traces, we propose a Seasonal Autoregressive Integrated Moving Average (SARIMA) model that generally fits the workload behavior of the MMOG cloud service. We implement our prediction-based algorithm that allocates resources according to predicted workload by SARIMA model. Finally, we evaluate impact of our proposed algorithm on the QoE, where experiments prove noticeable improvements.","PeriodicalId":345854,"journal":{"name":"2016 5th International Conference on Multimedia Computing and Systems (ICMCS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128305844","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}

By adjusting the dimensions of the monopole and slot, three desired resonant frequencies can be achieved and tuned independently. The antenna exhibits three resonances covering the 2.1-GHz band, 5.2/5.8 GHz WLAN bands and 3.5/5.5 GHz WiMAX bands.

It has recently become an area of attractive research interest. MWSNs have been attracting increasing interest for supporting a new generation of ubiquitous computing systems with great potential for many applications. However, the communication paradigms in this type of network differ from the ones associated to traditional wireless networks, triggering the need for efficient wireless communication technology. Several wireless technologies have emerged ranging from short and medium distance. Bluetooth, ZigBee and Impulse Radio Ultra Wide Band (IR-UWB) are three popular wireless communications technologies. Due to its various features and advantages (especially low power consumption and low complexity), IR-UWB is a key solution for MWSNs. In this paper, we study and evaluate the performance of IR-UWB for WSNs. We used MiXiM platform under OMNet++ simulator, to analyze and evaluate the main features and advantages of this new technology in terms of transmission time, data coding efficiency and power consumption.","PeriodicalId":345854,"journal":{"name":"2016 5th International Conference on Multimedia Computing and Systems (ICMCS)","volume":"265 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122629860","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}

Because of their limited resources, running sophisticated applications on mobile handsets could result in poor performances and shortened battery lifetime. One promising solution is computation offloading to the cloud. It permits to enhance both QoS and battery life of mobile terminals. In this paper we present a novel offloading decision algorithm that decides about offloading mobile computation to Cloud-RRH, i.e RRH with additional computational and storage resources located in the cloud. The proposed offloading algorithm incorporates a multitude of parameters in the offloading decision process while diminishing the mobile handset energy consumption and keeping a good user quality of experience by reducing application's response time. Simulation shows that the proposed algorithm is able to assure the computation of all the applications while respecting latency constraints and to prolong the mobile handset battery life.","PeriodicalId":345854,"journal":{"name":"2016 5th International Conference on Multimedia Computing and Systems (ICMCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131240922","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}
