Due to the proliferation of handheld mobile devices, multimedia applications like Voice over IP (VoIP), video conferencing, network music, and online gaming are gaining popularity in recent years. These applications are well known to be delay sensitive and resource demanding. The mobility of mobile devices, running these applications, across different networks causes delay and service disruptio...

We analyze the behavior of closed product-form queueing networks when the number of customers grows to infinity and remains proportionate on each route (or class). First, we focus on the stationary behavior and prove the conjecture that the stationary distribution at non-bottleneck queues converges weakly to the stationary distribution of an ergodic, open product-form queueing network. This ope...

It is well–known that TCP often experiences severe performance degradation in mobile networks since due to host mobility, packet losses not related to network congestion occur frequently. In this paper, we propose a buffering of packets at a base station to resolve such a problem. Our method can be used without sacrificing the scalability in Mobile IP based networks. For this purpose, we first ...

In this paper ANT colony optimization algorithm has been proposed to solve FPGA routing in FPGA design architecture with minimum umbers of tracks per channel. In our method geometric FPGA routing task is transformed into a Boolean satisfiability (SAT) equation with the property that any assignment of input variables that satisfies the equation specifies a valid route. The satisfiability equatio...

Traditional tour route planning mostly depends on the planner’s experience. However, whether tour route planning is appropriate or not has a considerable impact on the time and cost of the tour. Good planning can save unnecessary waiting time, avoid wasted operating costs, and contribute to the enhancement of the quality of tourism. Therefore, this study applied the ant colony optimization algo...

Traditionally, the selection of a pipeline route for offshore applications has been manually performed by the engineer, by a quick inspection of the seabottom bathymetry and the available information regarding obstacles. Eventually the evaluation of a given route could be performed using analysis tools, but in any case the process is highly dependent on the expertise of the engineer. In this co...

Prefix delegation-based schemes have been proposed to solve the route optimization problem in NEtwork MObility (NEMO) where multiple IP-enabled hosts move together as a mobile network. Differences in the route optimization for hosts at the cost of increased signaling will result in performance difference of the schemes depending on parameters, such as speed of the mobile network, its distance f...

Wayfinding, i.e. getting from some origin to a destination, is one of the prime everyday problems humans encounter. It has received a lot of attention in research and many (commercial) systems propose assistance in this task. We present an approach to route directions based on the idea to adapt route directions to route and environment's characteristics. The lack of such an adaptation is a majo...
