In relation to its growth in size and user population, the Internet faces new challenges that have triggered the proposals of value-added network services, e.g., IP multicast, IP ...
A cognitive radio (CR) network is often described as a secondary network operating in a frequency band originally licensed/allocated to a primary network consisting of one or multi...
— In this paper, we address a sensor network lifetime problem that maintains a certain throughput in an environment where physical node destruction is possible. While lifetime is...

—Today, most routing problems are solved using Dijkstra’s shortest path algorithm. Many efficient implementations of Dijkstra’s algorithm exist and can handle large networks ...
— We study the complexity of a spectrum of design problems for optical networks in order to carry a set of demands. Under wavelength division multiplexing (WDM) technology, deman...
