Video transmission combines large quantities of data with real-time requirements, two constraints which are hard to meet in low-power wireless multi-hop networks. This position paper presents experimental results of multi-hop video transmission in an IEEE802.15.4-based wireless network, using a protocol stack based solely on standards which are being finalized. This practical look allows us to ...

It is well known that the use of cache memory significantly improves the performance of a computing system. There exists a large quantity of technical literature dealing with analysis and design of cache-based systems. One of the most recent trends in computer technology is to implement multilevel caches. Today, most new processors implement an on-chip dual cache; one for instructions and one f...

Welcome to Atlanta, Georgia and to the 24th International Parallel and Distributed Processing Symposium. It has been my honor to spend several years of planning for Georgia Institute of Technology to host this event and to work with the Computer Society and our veteran volunteer team to make this week a reality. The success of this symposium is a direct result of the hard work and contributions...

In these notes we first offer an overview of two core areas in the dynamics of probability measure preserving systems, the Kolmogorov-Sinai theory of entropy and the theory of orbit equivalence. Entropy is a nontrivial invariant that, said simply, measures the exponential growth rate of the number of orbits in a dynamical system, a very rough measure of the complexity of the orbit structure. On...

In contrast to qualitative linear temporal logics, which can be used to state that some property will eventually be satisfied, metric temporal logics allow to formulate constraints on how long it may take until the property is satisfied. While most of the work on combining Description Logics (DLs) with temporal logics has concentrated on qualitative temporal logics, there has recently been a gr...
