Redundancy Scheduling with Locally Stable Compatibility Graphs [PDF]
Redundancy scheduling is a popular concept to improve performance in parallel-server systems. In the baseline scenario any job can be handled equally well by any server, and is replicated to a fixed number of servers selected uniformly at random.

Application of Traffic Weighted Multi-Map Optimization Strategies to Traffic Assignment
Traffic Assignment Problem (TAP) is a critical issue for transportation and mobility models that deals mainly with the calculus and delivery of best-cost routes for the trips in a traffic network.

Providing Dynamic TXOP for QoS Support of Video Transmission in IEEE 802.11e WLANs [PDF]
The IEEE 802.11e standard introduced by IEEE 802.11 Task Group E (TGe) enhances the Quality of Service (QoS) by means of HCF Controlled Channel Access (HCCA). The scheduler of HCCA allocates Transmission Opportunities (TXOPs) to QoS-enabled Station (QSTA)

On Stochastic Models of Traffic Assignment [PDF]
This paper contains a quantitative evaluation of probabilistic traffic assignment models and proposes an alternate formulation. First, the concept of stochastic-user-equilibration (S-U-E) is formalized as an extension of Wardrop's user-equilibration criterion.

A topology-based bounded rationality day-to-day traffic assignment model
This paper analyzes the day-to-day adjustment process of users’ behaviors in a transport network which is affected by relevant alterations such as disruptions due to critical events which cause the impossibility to use one or more links. For representing

A zone-based traffic assignment algorithm for scalable congestion reduction
Traffic assignment networks are networks with pseudo-static behavior: the network topology is constant but the cost of each edge changes in real-time. Extensive work has been completed in the literature to develop efficient traffic assignment algorithms ...

The Control Effect of Traffic Information on Traffic Assignment
The VISSUM and VISSIM simulation models are setup according to the real road network of Park City, Utah, U.S. The OD matrix is calibrated by the field turning counts. The effects of in-trip real-time information on traffic improvement are studied through microsimulation. Tests have shown that under adaptive traffic control signal, the in-trip real time

A mesoscopic traffic simulation based dynamic traffic assignment
In terms of sustainability, traffic is currently a significant challenge for urban areas, where the pollution, congestion and accidents are negative externalities which have strongly impacted the health and economy of cities. The increasing use of private vehicles has further exacerbated these problems.
