We consider the problem of optimizing traffic flow in a fixed network of wired and wireless links where some wireless links interfere with each other. The objective of the network operator is to maximize the total amount of traffic carried. We present algorithms for computing traffic flow in in a mixed wired-wireless network to meet demand and maximize the total traffic carried.

Because mobile phones are omnipresent and equipped with displays, they are attractive platforms for rendering 3D images. However, because they are powered by batteries, a graphics accelerator for mobile phones should dissipate as little energy as possible. Since external memory accesses consume a significant amount of power, techniques that reduce the amount of external data traffic also reduce...

we consider a grid network where nodes contain small buffers. a packet that faces a crowded buffer in its route will get extra latency and may be dropped. in this paper, we propose a novel flow control protocol called rfcc for grid networks. rfcc tries to reroute delayed packets and utilizes network coding to introduce a configurable amount of redundant information in the network, thereby incre...

background and purpose :cost-benefit equations is one of the most important by of gnp and a training a sustainable development as designated by professionals of occupational health .therefore ‚ drivers as a forgotten index in sustainable development and its effect on community health. methods & material : this descriptive analytical study involved the statistical community of 55000 vehicles in ...

Traffic congestion is one of the most severe problems in modern urban areas. Besides amplified travel times, traffic intensifies amount emitted pollutants impacting human heal ...

We have been witnessing an exponential growth in the amount of traffic carried through mobile networks. According to the Cisco visual networking index [1], mobile data traffic has doubled during 2010–2011; extrapolating this trend for the rest of the decade shows that global mobile traffic will increase 1000x from 2010 to 2020. The surge in mobile traffic is primarily driven by the proliferatio...

The use of IP traffic prediction techniques for DAMA TDMA protocols is investigated in this paper. The predicted traffic distribution is derived when the input traffic shows long-range dependence features. Furthermore, an equivalent bandwidth is calculated, which allows the wireless terminal to request a certain amount of bandwidth (slot duration) in terms of a target traffic loss probability. ...

An enormous amount of cellular data traffic has been produced by mobile users which exceeds the capacity of cellular network and hence weaken the network quality. The solution is to enhance the capacity of cellular networks which however is expensive and inefficient. As DTNs and Wi-Fi hotspots usually focus on maximizing the amount of cellular traffic that can be offloaded. In most cases due to...

In real networks, traffic flows are different in amount as well as their priorities. However, the latter priority has rarely been examined in routing strategy studies. In this paper, a novel routing algorithm, which is based on the efficient path routing strategy (EP), is proposed to overcome network congestion problem caused by large amount of traffic flows with different priorities. In this s...
