Distance ADaptive (DAD) Broadcasting for Ad Hoc Networks

In mobile ad hoc networks, it is often necessary to broadcast control information to all the constituent nodes in the network. Possible applications include searching for a destination node (as a part of routing) or a particular service such as DNS look-up. Flooding, which is often deployed to achieve the above objective, is expensive in terms of overhead and wastes valuable resources such as b...

On the improvement of the enhanced distance-based broadcasting algorithm

Energy efficiency has attracted a lot of attention during the recent years, especially in mobile ad hoc networks where devices rely on batteries. Moreover, in this kind of networks the cooperation among devices forwarding packets or acting as a router is crucial for the network performance. Thus, reducing the energy consumption of each sending is a key feature that has been widely studied. In t...

Distance Is Dead , Long Live Distance

For many educators, the phrase ‘from distance education to e-learning’ conjures up the view of an ‘evolutionary’ progression beginning with correspondence study and developed through more sophisticated technologies to its current identification with computers, the Internet, and the World Wide Web. For others, particularly those with little knowledge or experience of (and often equally little in...

Long distance transport.

A few years ago, I attended a 1-day symposium on long distance transport at a national meeting in a country abroad. Towards the end of the day, as the participants became tired and no general agreement was in sight, one observer from an allied discipline remarked, "Why can't you translocation workers make any progress, you still discuss the same miserable old models that were proposed 40 years ...

Long distance tunneling

Quantum tunneling between two potential wells in a magnetic field can be strongly increased when the potential barrier varies in the direction perpendicular to the line connecting the two wells and remains constant along this line. A periodic structure of the wave function is formed in the direction joining the wells. The resulting motion can be coherent like motion in a conventional narrow ban...
