    Background subtraction algorithm for moving object detection
    (Wydawnictwo Politechniki Łódzkiej, 2016) Saoud, Ayoub; Mosorov, Volodymyr; Grudzień, Krzysztof
    Background subtraction technic is a very important part of computer vision applications for successful segmentation of objects from video sequences. In this paper, a segmentation method for moving object using automated moving object detection in a video image sequence based on background subtraction method. Noise is applied to assess the robustness of the algorithm. The background model method and adaptive thresholding is used to compute the foreground object detection mask. A reference frame is initiatly used and considered as background information. Experimental results, which demonstrate the system's performance, are also shown.

    A load balancing system to protect servers against DDoS attacks
    (Wydawnictwo Politechniki Łódzkiej, 2016) Mbarek, Fatma; Mosorov, Volodymyr
    A Distributed Denial of Service (DDoS) aims at shutting down the services of intended servers with over-consumption of bandwidth or CPU processor and memory units, and considers the one of the hardest security problems in today's Internet. In this context, load balancing allows to distribute workloads among the processors, which provides a high protection in local area network (LAN) because it improves the quality of service and the performance. In this paper, we intend to present a load balancing system which is based on various algorithms and has as a main role to mitigate the impact of DDoS attacks.

    Performance evaluation of multi-protocol label switching (MPLS) over IP
    (Wydawnictwo Politechniki Łódzkiej, 2016) Mbarek, Fatma; Mosorov, Volodymyr
    Networks have evolved in terms of infrastructure and configuration incorporating new technologies and adapting them to take account of the need for technicality and compatibility with the rapid changes taking place in the world. MPLS (Multi Protocol Label Switching) is a versatile solution (based on QoS) to solve the problems addressed by the present networks like IP (Internet Protocol). In this chapter, we evaluate IP /MPLS networks in terms of performance, using several criteria of QoS. These criteria include: delay variation (average delay and delay), through put and loss rates. We evaluate through several types of flow (data, voice, video). To simulate IP/MPLS topology, we use the NS-2 simulator.
