Mobile users want to be connected to a network at any time for mobile computing applications, such as thin-client communications and network games, even while they are moving toward their destinations. They could take an alternate route (called a “longcut” route) if the route is geographically longer than a shortcut route to their destinations(More)
Several task forces are currently working on how to design the future Internet and it is high time for research work to also move a step forward to future mobile networks on a large scale. In this article, we propose a future mobile network management method based on a combination of OpenFlow and the biologically inspired attractor selection method to(More)
In this paper, we propose a novel mobility assisted, adaptive broadcast routing mechanism called Mobility Tolerant Firework Routing (MTFR) that improves node reach ability especially in situations with high mobility. We evaluate our proposal by simulations with the random walk and random waypoint mobility models and disclose tendencies that can be observed(More)
Network resources for mobile users such as available bandwidth fluctuate depending on the level of background traffic. The deployment of many access points enables mobile users to access more network resources on their way to their destination by taking the longcut route rather than the shortcut route. These users pay some extra cost to take the longcut but(More)
Several task forces have been working on how to design the future Internet in a clean slate manner and mobility management is one of the key issues to be considered. However, mobility management in the future Internet is still being designed in an “all-in-one” way where all management functions are tightly kept at a single location and this results in cost(More)
As Internet of Things (IoT) and smart devices are becoming widespread, expectations for large-scale ad-hoc networks are increasing. To accommodate a large number of nodes, ad-hoc networks should use multiple channels. Thus, dynamic channel switching methods in multi-channel ad-hoc networks have been investigated to control congestion of the channel.(More)
Several task forces have been working on how to design the future Internet and it is high time for research work to move a step forward to networks on a large scale. In this paper, we propose a future mobile network architecture on a combination of OpenFlow and the attractor selection method to achieve scalability and energy conservation. In addition, we(More)
