Traditional ML, whereby data is sent to a server for training and processing using models, is becoming less suitable due to privacy concerns. Thus, distributed approaches such as Federated Learning(FL) are becoming more popular. In the latter approach, the model is sent to the clients, where it is trained using the client’s data. The updated model is sent to a server to be aggregated. FL is expected to be used extensively in wireless networks. Therefore, researchers are interested in optimizing Federated Learning for wireless networks. This paper aims to study the performance of FL in terms of accuracy and amount of data exchanged in a wireless network considering the impact of delay using different datasets. The accuracy of the FL model was found to be reliable when benchmarked to the centralized approach(less than 0.1 difference in accuracy). The data transfer size with FL was also significantly smaller than in the centralized approach for all the tested datasets.","PeriodicalId":389716,"journal":{"name":"2022 IEEE 6th International Symposium on Telecommunication Technologies (ISTT)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122236129","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}

It was possible to determine the mobility of the ionosphere by observing how the total electron content (TEC) changed over time. The study on TEC variation was conducted in 2008 and 2009 over Malaysia, where latitude ranged from 1° N to 8° E and longitude ranged from 95° to 120° E, with each year reflecting the same degree of solar activity. The hourly mean vertical TEC (VTEC) is used to monitor the difference of the TEC under various geomagnetic factors such as disturbance storm time (Dst), planetary 3-hour range index (Kp), and solar flux F10.7 variations. This paper considers four cases of geomagnetic disturbances were considered 9 March, 27 March, 4 September 2008, and 22 July 2009. A percentage deviation was calculated to further analyze the geomagnetic disturbances in the equatorial region on quiet days. Results showed the TEC during geomagnetic disturbances was lower than the quiet day, with the percentage deviations between -20% and 10%. An increment of TEC was shown after approximately 24 hours, which is in the storm recovery phase. Also found were that GPS-TEC reaches its highest around post noon and its lowest in the small hours of the morning.","PeriodicalId":389716,"journal":{"name":"2022 IEEE 6th International Symposium on Telecommunication Technologies (ISTT)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114620459","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 choice of sensor node location directly affects the sidelobe levels of the radiation beampattern, which can affect the energy efficiency of the WSN. Therefore, an Artificial Intelligence algorithm, i.e. the Backtracking Search Algorithm (BSA) has been developed and implemented to optimize the radiation beampattern performance by finding the suitable location of the sensor nodes based on the linear array sensor nodes arrangement. The proposed Modified BSA-based Linear Array (LinearBSA) shows a superior improvement compared to the conventional linear array (LFA) in desired performance, i.e. minimize sidelobe level (SLL) and adaptive main beam angle. Performance on 8-, 12-and 16-node LinearBSA shows an improvement in radiation beampattern performance particularly in SLL minimization in any desired adaptive main beam angle.","PeriodicalId":389716,"journal":{"name":"2022 IEEE 6th International Symposium on Telecommunication Technologies (ISTT)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125524180","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}

School Wi-Fi that is reliable, fast, and secure will empower teachers to maximize their use of the internet in the classroom. As part of its Malaysian Education Blueprint 2013-2025, the Ministry of Education has taken another initiative in order to provide an effective learning experience for Malaysian students. The program aims to give every Malaysian public-school access to high-speed Internet access and a virtual learning environment (VLE). Energy consumption is becoming more important in schools as their network infrastructure expands, not only from an environmental standpoint but also from a capital expenditure perspective. This paper proposes the cost and energy consumption model for fiber-to-the-school (FTTS) network. The developed model was used to assess the energy consumption of the FTTS network. For the cost assessment, there is not much different in the cost variation between different scenarios considered in the analysis. It was also found that subscription cost contribute the highest percentage of 69% in total FTTS cost compared to other network costs. Meanwhile in energy consumption assessment, it is been discovered that the FTTS through scenario with energy saving approach by considering the idle state of the network elements will save approximately 24.33%. The energy saving is improved when considering energy consumption model when the network elements are switched off during inactive hours which is approximately 66.67%.","PeriodicalId":389716,"journal":{"name":"2022 IEEE 6th International Symposium on Telecommunication Technologies (ISTT)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132907577","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}
