  • Optimization of IP Multicast Networks performance 
    Samia, Mireille I. (Notre Dame University-Louaize, 2001-06)
    Internet Multicast service extends the Internet point-to-point unicast delivery to a multi-point delivery. Multicasting means that a datagram is sent to multiple sites at more or less the same time. To support real-time multimedia, the minimization of delay without loosing the reliability of the network is required. To achieve this goal, we have proposed to change the architecture of a multicast one-stage network to a multicast hierarchical two-stage network. We have proved that by giving additional functionalities (such as back-up and error correction) to the intermediate sites (i.e. mrouters) ...
  • Performability in wireless sensors network 
    Eid, Fadi (Notre Dame University-Louaize, 2005)
    This thesis tackles Performability issues in Wireless sensors networks. Performability is a mission-specific measure of system effectiveness that seeks to combine the traditional reliability and performance measures of a system. Wireless Sensor networks consist of a huge number of small sensor nodes, which communicate wirelessly. These sensor nodes can be spread out in hard accessible areas by what new applications fields can be pointed out [13]. This thesis aims to provide wireless communication architecture for Petroleum installations, such as off shore platforms and on shore processing units, ...
  • Performance analysis of smart gateways in Fog Network 
    Khalil, Fadi Y. (Notre Dame University-Louaize, 2018)
    With the advancement in computing and wireless technologies, the world has witnessed a growing number of connected devices to the Internet at an unpretending rate. Fog computing emerges as an alternative solution to reduce the burden of Data Centers in traditional Cloud Computing and to support geographically distributed, latency sensitive, and QoS-aware IoT appliations. Fog Computing suggests, that the intelligence should move from the data centers to the edge of network. The main objective of this thesis is to determine the significance and feasibility of implementing a broker node between ...
  • Post Quantum Hybrid Network Security and Architecture 
    Essaye, Anthony (Notre Dame University-Louaize, 2021)
    Quantum Computers, the next wave of computing, and an emerging field in computer science have brought numerous advancements to problem solving and a quantum approach to programming a certain machine. This thesis tackles three main areas in the approach to quantum computers. First, the thesis provides a state-of-the-art review to Quantum computers/ Second it proposes a timeline for the progress of the technology and highlights the importance of early action. Finally, it focuses on the implications of such advancements on the current standards of network security. Specifically, it proposes ...
  • Reducing power consumption in wireless sensors networks 
    Azar, Edgard (Notre Dame University-Louaize, 2004)
    The emerging field of wireless sensor networks combines sensing, computation, and communication into a single tiny device. Through advanced mesh networking protocols, these devices form a sea of connectivity that uses any possible communication path by hopping data from one node to another in search of its destination. While the capabilities of any single device are minimal, the collection of hundreds of sensors offers major new technological possibilities. Examples of usage scenarios for these devices are real-time tracking and security monitoring, issues that will be studied in this thesis. ...
