This process is usually powered by a random access (RA) mechanism to share and allocate radio resources dynamically. Over the past years, telecommunication industry has witnessed a massive growth in the Internet of Things (IoT) technologies which continue to be rolled out around the world with different services and having a variety of requirements. However, when massive IoT (mIoT) devices attempt to access the network over a limited number of Random Access Channel (RACH) resources within a time frame, the network becomes overloaded, leading to a low performance of human to human (H2H) communication and Quality of Services (QoS) may not be assured. To solve the above problems, we propose a dynamic resource slicing and access class barring (ACB) mechanism using deep reinforcement learning (DRL) for a new RACH scenario to control and manage the resource dynamically. Simulation results prove that our proposed technique provides a fair RACH resource allocation for each class according to the available radio resource.","PeriodicalId":371663,"journal":{"name":"2021 International Conference on Information and Communication Technology for Development for Africa (ICT4DA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124827279","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}

Recent Researches have included these measurements in the route acquisition and selection process. However; separately measuring these parameters can lead to larger packet size as the number of measured parameter increase. Our objectives are 1) to propose a metric called weight that generalizes the quality of nodes, and use it in the best route selection process of the Ad hoc On-Demand Distance Vector (AODV) protocol. 2) To compare the two path quality measurement methods, namely- the product and summation methods. The paper presents mathematical proofs of why the multiplication method is better than the summation and simulation-based comparison of the two methods. The simulated route-request and reply packets of the AODV protocol are modified to use the generalized weight metric in the routing process. Simulation results show that the summation method produces higher delay and packet delivery than both the product method and the AODV protocols.","PeriodicalId":371663,"journal":{"name":"2021 International Conference on Information and Communication Technology for Development for Africa (ICT4DA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123551414","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}

Concise and consistent identifier names are crucial to program comprehension. Identifier names reduce the effort to understand the software, support software maintenance and improve source code quality. Despite these benefits, many software systems are known to have meaningless and inconsistent identifier names. One of the reasons that lead to inconsistent identifier names is lack of knowledge of identifier names already used to represent concepts in the software. To address this problem, this study proposes a new approach to automatically suggest part of identifier name. The approach aims to use spatial locality to identify and suggest next terms given identifier name prefix. Spatial locality, in this context, refers to the use of terms in close proximity of documents related to the software system. The performance of our proposed approach is evaluated using six open source software systems. The evaluation result shows that the spatial locality based approach suggests part of identifier names correctly with an average precision of 83.2% and average mean reciprocal rank (MRR) of 25.5%. Of the top four correct suggestions, more than half are ranked in the first and second place.","PeriodicalId":371663,"journal":{"name":"2021 International Conference on Information and Communication Technology for Development for Africa (ICT4DA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130801407","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 determinant factors of food insecurity in Ethiopia are multidimensional encompassing climate change, civil conflicts, natural disasters, and social norms. This study, hence, aims to identify risk factors and predict food security status at household level in North West Ethiopia using supervised machine learning techniques. To this end, a dataset was gathered from the Dabat Health and Demographic Surveillance and statistically interesting risk factors were identified using logistics regression at a threshold level of p<0.05. Three experiments were also conducted using random forest, support vector machine and decision tree (C4.5) to predict food security status at household level and the performance of each model was evaluated using accuracy, precision, recall, and f1- measure. As a result, the C4.5 algorithm is selected as the best appropriate supervised machine learning algorithm with 97.23% of recall, 91.58% of accuracy, 80.97% of f1-measure, and 69.38% of precision.

Because of the millimeter wave's short wavelengths, a large number of antennas may be placed in a compacted physical dimension to make a greater aperture and obtain a substantial gain in antenna arrays. Dirty paper coding (DPC) beamforming efficiently cancels the interference that the transmitter is aware of, resulting in increased capacity, energy, and spectral efficiency of mmWave enabled massive MIMO connectivity. However, the use of this techniques leads to complexity due to successive interference cancellation at detection when the number of users grow large. In this paper, a cooperative processing based multi-user precoding is presented for down-link mm-wave massive MIMO systems and thus cooperative precoding be implicitly designed by considering the digital beamforming solution which is obtained from the dirty paper after comparing the output of linear precoding schemes. The precoders are chosen and the system total rate is calculated based on the difficulty of detections based on user densities within virtual cells. Simulation results show that the proposed approach outperforms traditional digital beamforming in terms of sum rate.","PeriodicalId":371663,"journal":{"name":"2021 International Conference on Information and Communication Technology for Development for Africa (ICT4DA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126167274","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}

Recently, state-of-the-art approaches based on hybrid optimization techniques have been proven to be suitable for cost effective results. This work implements and presents a multi-objective novel hybrid method by combining Backtracking search optimization algorithm and Integer programming approach(BackIP). Unlike, some other approaches, BackIP is a test input data generation method which includes test data generation, mutation analysis, and test suite reduction simultaneously.

Three cascades recursive least square (RLS) and cascades normalized least mean square (NLMS) adaptive filters are developed and combined using convex combination scheme to reduce motion artifacts (MA) from the recorded PPG signal. Then, ML based spectral tracking algorithms is applied, to locate the spectral peak corresponding to HR. Four different supervised ML algorithms (Support Vector Machine, Decision Tree, K- Nearest Neighbor and Logistic Regression) are examined to track the spectral peaks and the decision tree out performs all three algorithms with an accuracy of 98.96%. Experimental results on the PPG datasets including 23 subjects used in the 2015 IEEE signal processing cup showed that the proposed approach has a very good performance by achieving an average absolute error (AAE) of 1.98 beats per minute (BPM) and the personal correlation coefficient of 0.9899.
