In this survey, several studies and research works that were introduced in the literature will be investigated, aided by the followed methodology and main concepts in addition to the main outcomes and conclusions. A comparison will be held between these studies based on different criteria & performance metrics. An evaluation that investigates the effect of using AM with cooperative diversity in wireless communication system performance in terms of SE and throughput aided with improvement values will be introduced. Furthermore; some key points that may be considered by the wireless designers to obtain effective cooperative and AM communication scheme will also be highlighted.","PeriodicalId":319529,"journal":{"name":"2015 1st International Conference on Telematics and Future Generation Networks (TAFGEN)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132529723","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}

Despite these considerable benefits, there are serious concerns and challenges about this new technology. The most important issue is related to security and privacy subjects in cloud-based environments. Furthermore, resource allocation, load balancing, data management, data availability, scalability, compatibility and interoperability are the other challenges in cloud-based environments that decrease efficiency and reliability of this technology. In this paper, challenges and concerns related to cloud-based environments have been identified and most appropriate current solutions for each challenge have been described.","PeriodicalId":319529,"journal":{"name":"2015 1st International Conference on Telematics and Future Generation Networks (TAFGEN)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134362913","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}

Cooperative spectrum sensing (CSS) is proposed to allow multiple secondary users (SUs) to scan the spectrum and verify the existence of primary user (PU). The sensing information of PU is sent by the collaborated SUs to a common fusion center to combine all the data and make a final decision on PU availability. Data aggregation is made by two different schemes, namely soft detection fusion (SDF) and OR-logic hard detection fusion (OR-HDF). In this paper, a new Genetic Algorithm with Multi-Parent Crossover-based SDF scheme (GA-MPC) is proposed and its performance is compared with that of Standard Genetic Algorithm based-SDF scheme (SGA). Computer results show that the GA-MPC outperforms SGA in terms of convergence performance and stability. Furthermore, GA-MPC outperforms SGA, other SDF schemes and the OR-HDF scheme as it can achieve greater detection probability given a probability of false alarm.","PeriodicalId":319529,"journal":{"name":"2015 1st International Conference on Telematics and Future Generation Networks (TAFGEN)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116977400","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 current-voltage characteristic and frequency response was measured for the APD with and without guard ring. With the guard ring around the perimeter of the diode junction, it shows a better performance for the maximum bandwidth but in contrast lower in responsivity. To enhance the bandwidth, the detection area and the PAD size for RF probing are optimized to 10 × 10 μm2 and 30 × 30 μm2, respectively, to decrease the device capacitance, the spacing of interdigital electrode is narrowed to 0.84 μm to decrease carrier transit time, and by cancelling the carriers photo-generated in the deep layer and the substrate because the carriers are slow diffusion carriers. As a result, the maximum bandwidth of 8 GHz was achieved along with a gain-bandwidth product of 280 GHz.","PeriodicalId":319529,"journal":{"name":"2015 1st International Conference on Telematics and Future Generation Networks (TAFGEN)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129877796","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}
