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 propose novel approaches to wireless network...
Levy Flight is a special kind of random walk model. According to the past studies, the foraging patterns of animals follow a Levy flight distribution. Delay and disruption Tolerant Network(DTN) is a special network adapted to a special restricted network communication environment. In this paper, we proposed a new DTN model: BirdNet, which is based on fast-moving sensor nodes installed on the birds...
In this paper, we present a new technique to improve the reliability of H-tree SRAM memories. This technique deals with the SRAM power-bus monitoring by using built-in current sensor (BICS) circuits that detect abnormal current dissipation in the memory power-bus. This abnormal current is the result of a single-event upset (SEU) in the memory and it is generated during the inversion of the state of...
In this paper, we introduce and evaluate ScaleMesh, a scalable miniaturized dual-radio wireless mesh testbed based on IEEE 802.11b/g technology- ScaleMesh can emulate large-scale mesh networks within a miniaturized experimentation area by adaptively shrinking the transmission range of mesh nodes by means of variable signal attenuators. To this end, we derive a theoretical formula for approximating...
