  • Minimizing communication delay in TCP/IP Networks 
    Ghanem, Pascale Y. (Notre Dame University-Louaize, 2001)
    The global Internet has experienced many years of sustained exponential growth doubling in size every nine months or faster [8]. Millions of users at tens of thousands of sites around the world depend on the global Internet as part of their daily work environment. This massive use of the Internet as well as the continuous interconnection of new groups arises many problems such as: packet loss, network congestion, insufficient bandwidth, increase in delay... In this thesis, we focus mainly on the problem of communication delay and bandwidth allocation. Our main goal is to find a way to minimize ...
  • On integrating Kalman filters with partial resequencing for real-time tracking systems 
    Yazbeck, Khalil Nazih (Notre Dame University-Louaize, 2001)
    This thesis deals with the communication network performance of the Automatic Vehicle Location (AVL) distributed database system. The Automatic Vehicle Location system is used to real-time track the movement of vehicles, traveling along a large geographical area. The full control of the movement of these vehicles requires the use of many communication systems such as Global Positioning system, Packet switching network and distributed database systems including vehicle position databases. The main goal of this thesis is to minimize the update response time in a real-time fully replicated distributed ...
  • 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, ...
