Scalable evacuation routing in a dynamic environment
Article history: Received 8 August 2016 Received in revised form 19 August 2017 Accepted 26 August 2017 Available online xxxx In emergency management, tools are needed so we can take the appropriate action at different stages of an evacuation. Recent wildfires in California showed how quickly a natural disaster can affect a large geographical area. Natural disasters can create unpredicted traff...
متن کاملNetwork Parameters Evaluation in Vehicular Ad-hoc Network (VANET) Routing Protocols for Efficient Message Delivery in City Environment
Abstract- Efficient message delivery in city environment is required to ensure driver’s safety and passenger’s comfortability. In cities of developed nations, routing of data in vehicular Ad hoc Network (VANET) faces many challenges such as radio obstacles, mobility constraints and uneven nodes distribution. These factors primarily makes communication between vehicles complex. To overcome and t...
متن کاملRevenue Management in a Dynamic Network Environment
We investigate dynamic policies for allocating scarce inventory to stochastic demand for multiple fare classes, in a network environment so as to maximize total expected revenues. Typical applications include sequential reservations for an airline network, hotel, or car rental service. We propose and analyze a new algorithm based on approximate dynamic programming, both theoretically and comput...
متن کاملDynamic Routing System (DRS): Fault Tolerance in Network Routing
We present a novel proactive routing algorithm that continuously searches for failures via frequent ICMP echo requests. Our approach differs from its predecessors in that it is proactive instead of reactive. That is, we continuously search for failures before they affect message transmissions. When a failure is detected, an alternative route is identified and used. The Dynamic Routing System (D...
متن کاملImproving network routing performance in dynamic environments
In this dissertation, we study methods for improving the routing performance of computer communication networks in dynamic environments. The dynamic environments we considered in this work include both network topology changes and traffic demand changes. In the first part, We propose a novel fast rerouting scheme for link state routing protocols. Link state routing protocols are widely used by ...
