We show that for every n-point metric space M and positive integer k, there exists a spanning tree T with unweighted diameter O(k) and weight w(T) = O(k · n1/k ) · w(MST(M)), an...
—Experimentation with mobile ad hoc network testbeds is preferred to simulations for performing high fidelity testing. But, at the same time, realistic experimentation with larg...
A coalition provides a virtual space across a network that allows its members to interact in a transparent manner. Coalitions may be formed for a variety of purposes. These range ...
