Traffic oscillation, stop and go traffic, is created by different reasons such as: sudden speed drop of leader vehicle. Stop and go traffic commonly is observed in congested freeways results in traffic oscillation. Many theories had been presented to define congestion traffic based on laws of physics such as: thermodynamics and fluid. But, these theories could not explain the complexity of driv...

Stop and go traffic that leads to oscillate traffic flow frequently is observed on congestion flow. Unexpected reasons such as lane – changing maneuvers, lower speeds of leader vehicle and moving bottleneck cause stop and go traffic and amplifying delay and environment impacts. Stop and go traffic exactly can’t be modeled by traffic models, and also car following models based on kinematic flow ...

In a multipath network with a naive traffic partitioning scheme, varied packet loss rates as well as varied delays on multiple paths could seriously reduce TCP bandwidth. We propose a scheme, called dial-controlled hash (DCH), for dynamically partitioning traffic flows across multiple paths. DCH allows for fine-grained load balance, minimizes path oscillation for each traffic flow, and does not...

We consider the problem of coordination via signaling in network congestion games to improve social welfare deteriorated by incomplete information about traffic flow. Traditional studies on signaling, which focus on exogenous factors of congestion and ignore congestion externalities, fail to discuss the oscillations of traffic flow. To address this gap, we formulate a problem of designing a coo...

This paper points out a phase effect with REDlike queue management algorithms and two-way TCP traffic. It is shown by simulation and measurement that the RED queue converges to a state of heavy oscillation in the presence of two-way bulk-data TCP traffic, causing suboptimal link utilization and service differentiation between in-profile and out-of-profile packets. Besides investigating the reas...

This dissertation studies the trade-off between route adaptation and persistence. OUf thesis is that adding route persistence to shortest-path routing can enhance network performance, especially under heavy traffic conditions. Shortest-path routing can cause route oscillation and instability, thereby increasing congestion and reducing the effective throughput of the network. To study the effect...

Based on the two-dimension cellular automaton traffic flow model (BML model), a mixed traffic flow model of urban traffic that considering the transit traffic is established in this paper by using theDon't block the box rules. We have investigated the influences of the transit traffic ratio, and found that, in most cases, the urban traffic flow exhibited jam phase. Moreover, focusing on the tra...

The Internet routers employing the random early detection (RED) algorithm for congestion control suffer from the problem of chaotic queue oscillation. It is well known that the slowly varying nature of the average queue size computed using an exponentially weighted moving average (EWMA) used in the RED scheme causes this chaotic behavior. This paper presents a new mathematical function to model...

We consider a queueing network of d single server stations. Each station has a finite capacity waiting buffer, and all customers served at a station are homogeneous in terms of service requirements and routing. The routing is assumed to be deterministic and hence feedforward. A server stops working when the downstream buffer is full. We show that a properly normalized d-dimensional queue length...
