We suggest that large-scale turbulence dissipation is concentrated along caustic networks (that appear due to vortex sheet instability in three-dimensional space), leading to an effective fractal dimension Deff = 5/3 of the network backbone and a turbulence intermittency exponent μ = 1/6. Actually, Deff < 5/3 and μ > 1/6 due to singularities on these caustic networks. It is shown (using the the...

Mobile entities with wireless links are able to form a mobile ad-hoc network. Such an infrastructureless network does not have to be administrated. However, self-organizing principles have to be applied to deal with upcoming problems, e.g. information dissemination. These kinds of problems are not easy to tackle, requiring complex algorithms. Moreover, the usefulness of pure ad-hoc networks is ...

Constructing a connected dominating set as the virtual backbone plays an important role in wireless networks. In this paper, we propose two novel approximate algorithms for dominating set and connected dominating set in wireless networks, respectively. Both of the algorithms are based on edge dominating capability which is a novel notion proposed in this paper. Simulations show that each of pro...

We examine the strategic interaction between interconnection and competition in the Internet backbone market. Networks asymmetric in size choose among different interconnection regimes, IP-Transit, Bill-and-Keep Peering, and Paid Peering, and compete for end-users. We show that sufficiently symmetric networks enter a Peering agreement while otherwise use an intermediary network for exchanging t...
