the current internet inherently has a degree of survivability due to the connection less ip protocol. dynamic routing protocols are designed to react to faults by changing routes when routers learn about topology changes via routing information updates (e.g., link status advertisements). loss of quality of service (qos) has not been an issue because current internet traffic is the best-effort. ...

| Models of achievable routing, i.e., chip wireability, rely on estimates of available and required routing resources. Required routing resources are estimated from placement, or (a priori) using wire length estimation models. Available routing resources are estimated by calculating a nominal \supply," then taking into account such factors as the e ciency of the router and the impact of vias. M...

Vehicular Ad-Hoc Networks can enhance road safety and enable drivers to avoid different threats. Safety applications, mobile commerce, and other information services are among different available services that are affected by dynamic topology, vehicle’s speed and node misbehaving. Dynamic topology makes the route unstable and unreliable. So, improving the throughput and performance of VANET thr...

one of the important issues in transportation and logistics systems is vehicle routing problem (vrp). the vehicle routing problem is concerned with finding efficient routes of minimum total cost, beginning and ending at a central depot, for a fleet of vehicles to serve a number of customers. on the other hand, as a result of the increasing environmental concerns, economic problems and pressure ...

stochastic approach to vehicle routing problem: development and theories abstract in this article, a chance constrained (ccp) formulation of the vehicle routing problem (vrp) is proposed. the reality is that once we convert some special form of probabilistic constraint into their equivalent deterministic form then a nonlinear constraint generates. knowing that reliable computer software for lar...

In this paper, the FPGA routing process is explored to mitigate and take advantage of the effect of delay variability due to process variation. A new method called partial rerouting is proposed in this paper to improve the timing performance based on process variation and reduce the execution time. By only rerouting a small number of critical and near-critical paths, about 6.3% timing improveme...

The hazardous materials risk management process involves a set of crucial logistical decisions referring to the planning of the hazardous materials transportation and the organization of the emergency response operations. The objective of this paper is to present a Decision Support System for hazardous Materials Transportation Risk Management that covers integrated hazardous materials distribut...

Unmanned Aerial Vehicles (UAVs) are gaining momentum in many civil and military sectors. An example is represented by the logistics sector, where UAVs have been proven to be able improve efficiency of process itself, as their cooperation with trucks can decrease delivery time reduce fuel consumption. In this paper, we first state a mathematical formulation Travelling Salesman Problem (TSP) appl...
