  • Virtual Traffic Lights: System Design and Implementation
    arXiv: Networking and Internet Architecture, 2018
    Co-Authors: Rusheng Zhang, Frank Schmutz, Kyle Gerard, Aurelicn Pomini, Louis Basseto, Sami Ben Hassen, Akihiro Ishikawa, Inci Ozgunes, Ozan K. Tonguz
    Abstract:

    Traffic congestion is a daunting problem that is affecting the daily lives of billions of people across the world. Recently, a promising new Traffic Control Scheme known as Virtual Traffic Lights (VTL) has been proposed for mitigating Traffic congestion. VTL is an infrastructure free Traffic Control Scheme that leverages the presence of Vehicle-to-Vehicle (V2V) communications. Such infrastructure free Scheme has several benefits, such as alleviating Traffic congestion; reducing the large cost of Traffic lights and Traffic Control systems; reducing carbon emission, etc. This paper reports a DSRC-based prototype design effort on VTL using Dedicated Short Range Communications (DSRC) technology. The experiments performed show the feasibility of implementing VTL with DSRC technology. Preliminary results of the field tests conducted in Pittsburgh with vehicles using VTL equipment indicate that VTL is capable of coordinating Traffic at intersections and reducing the commute time of people.

  • ILBO: Balance Inbound Traffic Dynamically in Multihomed Stub Networks
    IEEE Transactions on Parallel and Distributed Systems, 2010
    Co-Authors: Xiaomei Liu, Li Xiao
    Abstract:

    Multihoming load balancing improves network performance and makes better use of network resource by leveraging the Traffic among the access links in a multihomed network. Currently, no effective load balancing system is available to handle the inbound Traffic in a multihomed stub network, where the Traffic volume is unknown to the network and the route of the Traffic is hard to Control. In this paper, we propose ILBO, an inbound Traffic load balancing mechanism to effectively balance the inbound Traffic in a multihomed stub network. ILBO predicts and schedules the inbound Traffic based on outbound Traffic. It adopts a two-step Traffic predictor to increase the prediction accuracy and also provides an inbound Traffic Control Scheme that can guarantee the successful execution of the Traffic scheduling. We have evaluated the effectiveness of ILBO in a trace driven simulation with real world Traffic traces collected from multihomed stub networks.

    Abstract:

    Multihoming load balancing improves network performance by leveraging the Traffic among the access links in a multi-homed network. Currently, no effective load balancing system is available to handle the inbound Traffic in a BGP multi-homed stub network, where the Traffic volume is unknown to the network and the route of the Traffic is hard to Control. In this paper, we propose ILBO, an inbound Traffic load balancing mechanism to effectively balance the inbound Traffic in a BGP multi-homed stub network. ILBO predicts and schedules the inbound Traffic based on outbound Traffic. It also provides an inbound Traffic Control Scheme that can guarantee the successful execution of the Traffic scheduling.

  • a novel vehicular Traffic Control Scheme for connectivity improvement in vanets
    Global Communications Conference, 2018
    Co-Authors: Maurice Khabbaz, Elie Saad, Joe Kodsi
    Abstract:

    Establishing a continuous multi-hop data communication path among an arbitrary pair of vehicular nodes is severely affected by the natural vehicular Traffic's restrictive mobility dynamics (e.g. flow rate, speed, direction of movement, etc). This paper proposes a novel Vehicular Traffic Control (VTC) Scheme that has the objective of regulating the vehicles' speeds in a way to get them steadily navigating in the proximity of each other at inter-vehicular distances that do not exceed their respective OnBoard Units' ranges. This triggers the formation of robust and long-lived communication links connecting the vehicles together; hence, increasing the path availability probability. A mathematical framework is established to evaluate the performance of VTC in terms of crucial Quality-of-Service (QoS) metrics such as the path availability and average end-to-end packet delivery delay. The validity and accuracy of the proposed model is verified through simulations. The reported results constitute a tangible proof of the benefits/merit of VTC in the context of a vehicular networking scenario characterized by low-to-medium flow rates.
