., data delivery delay) on a two-way road segment for carry-and-forward data delivery schemes in vehicular networks.  ...  In the near future, more vehicles will be equipped with DSRC devices because of governmental policies for driving safety. In this paper, we derive link delay model on a two-way road segment.  ...  Note that the vehicle inter-arrival time is the reciprocal of vehicle arrival rate λ. As shown in Fig. 4 , one-way simulation result has longer delay than twoway simulation result.  ...

TMA: Trajectory-based Multi-Anycast forwarding for efficient multicast data delivery in vehicular networks

Jaehoon (Paul) Jeong, Tian He, David H.C. Du
2013 Computer Networks  
To our knowledge, this is the first attempt to investigate the efficient multicast data delivery in vehicle networks, based on the trajectories of vehicles in the multicast group.  ...  For each target vehicle in the multicast group, multiple packet-and-vehicle rendezvous points are computed as a set of relay nodes to temporarily hold the data, considering the vehicle's trajectory.  ...  This is because the high vehicle speed yields high vehicle arrival rate at each road segment, leading to the shorter delivery delay.  ...

2003 Simulation (San Diego, Calif.)  
This research focuses on a specific class of Hybrid Fiber Coaxial (HFC) residential Internet access system. Such systems have three separate traffic classes: voice, modem, and high-speed data.  ...  This work studies the delay effects resulting from heterogeneous traffic types competing for communications resources on a prioritized shared medium using a fixed access and admission control scheme.  ...  However as the number of modem users is reduced in favor of high-speed data users, we note that the queueing delay quickly dissipates to a level at least an order of magnitude less than the single high-speed  ...
