    Formal Trust Assessment with Confidence Probability
    (KSII-KOR SOC INTERNET INFORMATION, 2015) Mahir Kutay; Tuncay Ercan; Ercan, Tuncay; Kutay, Mahir
    Trust and trustworthiness of web services and organizations is calculated as scalar values. But there is still a certain level of risk for the overall reliability of this value. In this article we focus on calculating trust values as intervals between upper and lower bounds based on predefined confidence values through an additional confidence probability. This will give us a more realistic approach to the trust assessments between individuals and organizations. We also developed a web-based software tool TAST (Trust Assessment Software Tool) that collects the web services' evaluation of different customer groups for similar organizations through the user interface and calculates the trust intervals for predefined and previously selected confidence values. Our model uses a weighted calculation of mean and variances of customer groups in specific periods and analyses the total and incremental trust of different customer groups.

    İsimli veri ağlarında yönlendirme ve önbellek güvenilirliği
    (2014) Sulaiman, Yakubu Yunusa; Ercan, Ahmet Tuncay
    İsimli veri ağları (Named Data Networking-NDN) mimarisi mevcut kullanıcı tabanlı yönlendirmeyi, ağ topolojisi üzerinde ölçeklenebilir içerik dağıtımı için ağdaki önbellek kullanımıyla birlikte isim tabanlı yönlendirme ile değiştirmeyi önermektedir. NDN yönlendirmesinde IP adresleri değil, önbellek kullanımından dolayı çok yönlü yönlendirmeyi ve akıllı içerik dağıtımını destekleyen değişken kapasiteli isim önadları kullanılır. NDN günümüz veri ağlarında kullanılan yönlendirme düzeneğinin özellikleri arttırılmış bir uygulaması olup, geçerli yönlendirme protokolleri ya isme dayalı olarak ya da ilk defa olarak önerilmektedir. Yönlendirme ve verinin önbelleğe alınması yönlendirici cihazlar üzerinde kullanılacak üç farklı tablo ile sağlanmaktadır: Veri deposu (Content Store), Bekleyen İstek Tablosu (PendingInterestTable - PIT), ve Yönlendirilen İstek Tablosu (Forwarding Information Base – FIB). Bu tabloların her biri yüksek performanslı bir yönlendirme ve veri önbellek kullanımı için ciddi bir bakıma ihtiyaç duymaktadır.Özellikle, NDN yönlendiricilerdeki önbellek kullanımı özel dikkat gerektirir. Bundan dolayı, bu tez çalışması kapsamında Bekleyen İstek Tablosu(PIT) üzerindeki veriyi azaltacak stratejiler üzerinde durulmuş ve farklı kullanım politikalarındaki önbellek performansları araştırılmıştır.

    Prediction based cost estimation technique in agile development
    (Elsevier Ltd, 2023) Shariq Aziz Butt; Tuncay Ercan; Muhammad Hatim Binsawad; Paola Patricia Ariza-Colpas; Jorge L. Díaz-Martínez; Gabriel Piñeres-Espitia; Emiro De-La-Hoz-Franco; Marlon Alberto Piñeres-Melo; Roberto Cesar Morales-Ortega; Juan David De-la-Hoz-Hernández; Pineres-Espitia, Gabriel; Binsawad, Muhammad; Ariza-Colpas, Paola-Patricia; Ercan, Tuncay; De-La-Hoz-Hernandez, Juan-David; Diaz-Martinez, Jorge; Butt, Shariq Aziz
    Agile has been invented to improve and overcome the deficiencies of efficient software development. At present the agile model is used in software development vastly due to its support to both developers and clients resourcefully. Agile methodology increases the interaction between the developer and client to make the software product defect-free. The agile model is getting to be a well-known life cycle model because of its particular features and most owing is to allow changes at any level of the project from the product owner. However on other hand this novel feature is a disadvantage of the agile model due to frequent change requests from the client has increased the cost and time. To overcome cost and time estimation issues different cost estimation techniques are being used in agile development but no one is pertinent for accurate estimation. Therefore this study has proposed a cost estimation technique. The proposed estimation technique is predictions-based and has different categorizations of projects based on user stories complexities and the developer's expertise. We have applied the suggested technique to ongoing projects to find the results and effectiveness. We have used two projects with different sizes and user stories. Both projects have different modules and developers with different expertise. We have used the proposed estimation technique on projects and done a survey session with the teams. This survey session's main objective is to reveal the statistical findings of the proposed solution. We have designed the 12 hypotheses for statistical analysis. © 2022 Elsevier B.V.

    A Framework Model for Data Reliability in Wireless Sensor Networks
    (IEEE, 2016) Ilker Kalayci; Tuncay Ercan; Ercan, Tuncay; Kalayci, Ilker
    In this study a model for data reliability in wireless sensor networks is proposed in which machine learning methods are used. Proposed framework includes data modelling missing data prediction anomaly detection data fusion and trust mechanism phases. Thus temporal analysis is performed on the preprocessed sensor data and missing data are predicated. Then outliers on collected data are detected on the cluster head nodes by using Eta one-class Support Vector Machines. If an event is detected data are fused and then send to sink. If an anomaly is detected for a node's data the trust weight of the node is decreased.
