We offer a powerful peer-to-peer scheme for the efficient organization of very large scale dynamically distributed systems such as ad hoc mobile networks and computer grids. The architecture is realized as a logical overlay of a two-dimensional concentric multi-ring topology (illustrated above) with the best robust resource distribution and discovery algorithm available. The latter allows no more than DHiPeer steps to retrieve any resource in the network with DHiPeer = logd (N(d-1) +d) -1, where DHiPeer is the minimum diameter (distance between nodes), d is a given fixed maximum degree (connectivity) of each node and N is the number of nodes. Each node holds a routing table of constant size 2d + 3 and can join or leave the network for a controlled constant cost ~O(d) which is independent of the number of nodes in the network. This solution does not exhibit the typical disadvantages of common computation and communication architectures such as high bandwidth consumption, centralized directory structure and non-consistent distribution of resources. It is fast, reliable and cost efficient and can be implemented in systems of unlimited size.<br><br> <p><strong>Benefits</strong><br> <ul type="disc">

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
