In particular, inefficient energy utilization has remained a core critical challenge as sensor nodes are naturally resource constraint and mostly deployed in unattended environments. This challenge has a direct impact on SDWSN performance and reliability. Albeit, several techniques have been proposed and developed to address the challenge in the traditional WSN and few for SDWSN, optimal efficient energy utilization is yet to be achieved. Therefore, this paper survey some of the energy efficiency techniques reported in the literature. The goal is to gain insights into these techniques, strategies employed, their pros and cons which could be utilized to design an efficient-energy mechanism for SDWSN. The findings obtained show that the existing approach ensures efficient energy utilization and improve network performance. While some have routing protocol and security mechanisms, fault tolerance, and battery fault detector mechanisms are not incorporated.","PeriodicalId":349926,"journal":{"name":"2020 2nd International Multidisciplinary Information Technology and Engineering Conference (IMITEC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132426231","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}

One of the most significant discussions in higher education is student attrition in their first year of study. Student career guidance is an area that requires investigation in light of high attrition rates at university. Recent developments in data analytics, and the analysis of large data sets have enabled the production of powerful predictive models. This paper highlights how a predictive model can assist students, with an interest in Science to develop a skill profile required to be successful in their undergraduate Science programme. This is achieved by identifying the difference between the necessary skills required to be successful in a science programme (derived using data driven approaches) from the current learner's skill profile (derived from the learners' performance in assessments). The learners' skill profile is used to predict success in four Science streamlines. Based on the prediction results, we gauge the improvement in skills required to succeed in that programme. We provide the following contributions: (a) a trained classifier able to calculate the distribution over learners' success in Science streamlines focused around the notion of skill profiles; (b) a ranking of these skill profiles according to their information gain (entropy); and (c) an interactive program to calculate the posterior probability over these skill profiles given learner's pre-university observations. We argue that it is crucial that students gauge the focus areas of skill improvement prior to enrolling for their degree so that they can consider streams in Science degrees that are suited to their academic strengths.","PeriodicalId":349926,"journal":{"name":"2020 2nd International Multidisciplinary Information Technology and Engineering Conference (IMITEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130410455","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 benefit comes at a performance cost as it increases resource usage. Use of network-based intrusion detection systems allows intelligent interventions where complex encryption parameters are reduced. We propose a method for implementing adaptive adjustment of encryption parameters in the AES algorithm on a client and server platform. Precisely, an algorithm used to implement adaptive encryption is proposed for distributed systems, which optimizes both performance and dependability. In addition, we present an efficient decryption protocol to reverse adaptive encryption. Results show that the overall performance of the proposed algorithm can be monitored, keeping such performances at acceptable levels whilst security of data in transit is still maintained. System performance can also be increased when communication time differences between nodes in a distributed environment are captured as parameters to trigger adaptation of the algorithm to either use more or lesser number of encryption rounds.","PeriodicalId":349926,"journal":{"name":"2020 2nd International Multidisciplinary Information Technology and Engineering Conference (IMITEC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124906175","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 numerous uncertainty risk factors which characterises heart disease mean that the diagnosis of this disorder is a complex task, even for the experts. In an effort to decrease both the time required for disease diagnosis as well as to enhance the accuracy of the diagnosis, clinical decision support systems (DSS) have been developed that incorporate data mining techniques to enhance the disease diagnosis accuracy. When literature is investigated, it has been observed that different researchers report the classifier's performance based on the overall accuracy of the classifier. That is, most researchers would evaluate the classifier's performance and choose the best classifier based on its overall accuracy. The question raised by this study is “What if the best classifier based on the overall accuracy is not a good predictor of a particular class in question within the dataset?” This paper thus presented the diagnosis of heart disease risk level using classification techniques under the data mining approach. A detailed comparative study focuses on how different classifiers predict each heart-disease class during the process of disease diagnosis. The comparative study is discussed using the confusion matrix of each classifier.","PeriodicalId":349926,"journal":{"name":"2020 2nd International Multidisciplinary Information Technology and Engineering Conference (IMITEC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117115912","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}

LoRaWAN aims to provide long-range communication and empowers low-powered devices to last for years in the field. LoRaWAN relies on the symmetric cryptography to provide end-to-end encryption. Even though LoRaWAN relies on symmetric cryptography, there are recent works that try to enhance security of LoRaWAN by incorporating technologies like Blockchain. Blockchain is a decentralized peer-to-peer network that provides tamperproof and immutability of data. This paper proposes a Blockchain-based firmware update mechanism to enhance firmware update in LoRaWAN as well as managing the update process. This mechanism aims to provide updates by ensuring authenticity, and integrity of the firmware. The mechanism focuses more on devices that are too constrained in resources, hence for that purpose we evaluated the cost involved in some cryptographic operations taken to ensure security during firmware updates. We conclude that the approach is feasible for constrained devices in LoRaWAN network by evaluating the memory usage of the cryptographic operation used by the end device.","PeriodicalId":349926,"journal":{"name":"2020 2nd International Multidisciplinary Information Technology and Engineering Conference (IMITEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133893619","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}

Its introduction has brought about great and innovative changes in the way the computer network is designed, managed, and operated. Currently, SDN architecture can be deployed with a single centralized controller or multiple controllers. However, deploying a single controller to manage a large area network such as wide area networks is ineffective and not ideal since network performance requirements and good quality of service can't be achieved. This challenge is solved by deploying multiple controllers to eliminate single-point-of-failure, controller overload, transmission delay, and so on. Despite these, multi-controllers deployments come with controller placement problem (CPP) and several approaches have been proposed and developed to address it. Therefore, this paper conducted a review of some of the CPP for SDN with a focus on capacitated and uncapacitated schemes. We analyzed the schemes, classified them, and provide few future research directions aimed at improving the CPP scheme.","PeriodicalId":349926,"journal":{"name":"2020 2nd International Multidisciplinary Information Technology and Engineering Conference (IMITEC)","volume":"244 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134275798","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}

Previous research has shown that cybercriminals use different methods, including the DNS protocol, to distribute malicious content, remain hidden and avoid detection from various technologies that are put in place to detect anomalies. This allows botnets and certain malware families to establish covert communication channels that can be used to send or receive data and also distribute malicious payloads using the DNS queries and responses. Cybercriminals use the DNS to breach highly protected networks, distribute malicious content, and exfiltrate sensitive information without being detected by security controls put in place by embedding certain strings in DNS packets. This research undertaking analysed the use of the DNS in detecting domains and channels that are used for distributing malicious payloads. Passive DNS data which replicate DNS queries on name servers to detect anomalies in DNS queries was evaluated and analysed in order to detect malicious payloads. The research characterised the malicious payload distribution channels by analysing passive DNS traffic and modelled the DNS query and response patterns used during malicious payload distribution. The research found that it is possible to detect malicious payload distribution channels through the analysis of DNS TXT resource records.","PeriodicalId":349926,"journal":{"name":"2020 2nd International Multidisciplinary Information Technology and Engineering Conference (IMITEC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128188734","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}
