The dynamic topology of ad hoc networks makes route discovery and reconstruction a non-trivial task. In this work we propose the use of mobility prediction to assist in ad hoc routing. A method of route discovery and route reconstruction using the sectorized mobility prediction technique is presented. Simulation and analytical results of the proposed routing strategy find it to offer considerab...

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...

Over the last decade, the rapidly growing population of mobile data terminals, integrating GIS and GPS, has given rise to a new type of real-time spatiotemporal service called Location-Based Service (LBS). Routing is an important function of LBS and Geographic Information Systems for Transportation (GIST). It is used in many land-based transportation applications, such as the Intelligent Vehicl...

abdominal wall hernias are the most common situations requiring major surgeries. in this study, we report a large incisional hernia, as an incidental finding, in a tc-dtpa scan of a renal transplant recepient. increased flow of activity in dynamic phase and relatively increased and nonuniform tracer accumulation in static phase of the study were observed.

Transport xenobiotis throug tissues and organs was studied. The aim of this paper dynamic xenobiotic transfer and accumulation in the specific tissues and organs were investigated. Some of xenobiotics are suficiently soluble in blood to account for simple solution as a route of distribution. Many xenobiotics are distributed in association which plasma proteins. Cellular components are responsib...

We present an iterative algorithm to determine the dynamic user equilibrium for link costs given by a traac simulation model. Each driver's route choice is modelled by a discrete probability distribution which is used to select a route in the simulation. After each simulation run, the probability distribution is adapted to minimize the perceived costs. As an example application, a dynamic versi...

This paper develops a method for solving the single product multi-period production-planning problem, in which the production and the inventory costs of each period arc concave and backlogging is not permitted. It is also assumed that the unit variable cost of the production evolves according to a continuous time Markov process. We prove that this production-planning problem can be Stated as a ...

A key factor deciding the performance of a routing protocol in mobile ad hoc networks is the manner in which it adapts to route changes caused by mobility. Exploiting the intuition that a less dynamic route lasts longer, we propose a new metric, the Route Fragility Coefficient (RFC), to compare routes. RFC estimates the rate at which a given route expands or contracts. Expansion refers to adjac...
