  • Dynamic Multi Threshold Priority Packet Scheduling Algorithms 

    Authors:Daǧ, Tamer; Uzungenc, Sezer
    Publisher and Date:(EDP Sciences, 2015)
    Packet scheduling algorithms are developed in order to use shared transmission resources efficiently. Various application packets such as real and non-real time packets might have different QoS requirements and traditional scheduling algorithms might be insufficient to respond to the applications needs. In this paper two packet scheduling algorithms are proposed to overcome this problem: Dynamic multi threshold priority packet scheduling (DMTPS) and dynamic multi threshold priority with urgency ...

  • Methods to improve recommender systems in e-commerce and e-learning environments 

    Authors:Jabakji, Ammar
    Publisher and Date:(Kadir Has University, 2017)
    Recommendation systems play a critical role in the information Science application domain especially in e-commerce ecosystems. in almost all recommender systems statistical methods and machine learning techniques are used to recommend items to the users. Although the user-based collaborative filtering approaches have been applied successfully in many different domains some serious challenges remain especially in regards to large e-commerce sites for recommender systems need to manage millions of ...

  • Protecting openflow switches against denial of service attacks 

    Authors:Bahaa-Eldin, Ayman M.; ElDessouky, Ebada Mohamed Essam Eldin Ibrahim; Daǧ, Hasan
    Publisher and Date:(Institute of Electrical and Electronics Engineers Inc., 2018)
    This paper presents a novel approach to protect Openflow switches against a type of Denial of Service (DoS) attacks. Openflow switches are the core of Software Defined Networks (SDN) and they are very flexible programmable and can be used for several functionalities within a network. As the control algorithm of the switch is implemented on a separate computer (Controller) this software can be implemented on any part of the network packet including Layers 2 3 and 4 headers. Therefore an Openflow ...
