    Convergence, stability and robustness analysis of the OFEX controller for high-speed networks

    The OFEX (Optimal and Fully EXplicit) rate controller is able to provide not only the optimal bandwidth allocation but also the fully explicit congestion signal to sources. It exercises link-wise proportional ...

    Location Prediction of Vehicles in VANETs Using A Kalman Filter

    Location information is very important for many applications of vehicular networks such as routing, network management, data dissemination protocols, road congestion, etc. If some reliable prediction is done o...

    Using interval phase margin assignment to self-tune a PI AQM controller for TCP traffic

    We propose a self-tuning PI (Proportional-Integral) controller for an AQM (Active Queue Management) router supporting TCP traffic in the Internet. Classical control theory is applied in the controller design t...

    Tree-Based Distributed Multicast Algorithms for Directional Communications and Lifetime Optimization in Wireless Ad Hoc Networks

    We consider the problem of maximizing the network lifetime in WANETs (wireless ad hoc networks) with limited energy resources using omnidirectional or directional antennas. Unlike most solutions that use a cen...

    Self-tuning Optimal PI Rate Controller for End-to-End Congestion With LQR Approach

    This paper presents a self-tuning optimal PI (Proportional-Integral) rate controller for end-to-end congestion in the IP-based Internet. We employ LQR (Linear Quadratic Regulator) approach from modern control ...

    A Lagrangian-Relaxation Based Network Profit Optimization For Mesh SONET-Over-WDM Networks

    In Wavelength Division Multiplexing (WDM) networks, the huge capacity of wavelength channels is generally much larger than the bandwidth requirement of individual traffic streams from network users. Traffic gr...

    Provisioning QoS guarantee by multipath routing and reservation in Ad hoc networks

    In this paper, a QoS multipath source routing protocol (QoS-MSR) is proposed for ad hoc networks. It can collect QoS information through route discovery mechanism of multipath source routing (MSR) and establis...

    The impact of non-Gaussian distribution traffic on network performance

    Recent extensive measurements of real-life traffic demonstrate that the probability density function of the traffic is non-Gaussian. If a traffic model does not capture this characteristics, any analytical or ...
