A distributed algorithm is presented that constructs the minimum-weight spanning tree in a connected undirected graph with distinct edge weights. A processor exists at each node of the graph, knowingâ€¦ (More)

We introduce a traffic model for circuit-switched all-optical networks which we then use to calculate the blocking probability along a path for networks with and without wavelength changers. Weâ€¦ (More)

We revisit the problem of evaluating the performances of communication systems with optical amplifiers and a wideband optical filter. We compute the exact probability of error and the optimalâ€¦ (More)

This work considers the achievable performance for coded systems adapted to a multipath blockâ€“fadingchannel model. This is a particularly useful model for analysing mobileâ€“radio systems which employâ€¦ (More)

An algorithm is given to find a prefix condition code that minimizes the value of the moment generating function of its codeword length distribution for a given positive argument. This algorithm isâ€¦ (More)

The problem of transporting constant bit-rate (CBR) traac through a packet network is analyzed. In the system considered, CBR traac is packetized and packets from several similar sources areâ€¦ (More)

A general framework is developed for analyzing a wide class of vehicle dispatching strategies for bulk arrival, bulk service queues. A simple derivation of the queue length transform for the imbeddedâ€¦ (More)
