Distributed applications and services requiring the transfer of large amounts of data have
been developed and deployed all around the world. The best effort behavior of the Internet …

In this paper we present some new, practical, geometric optimization techniques for
computing polygon partitions, 1D and 2D point, interval, square and rectangle covers, as …

In this paper I investigate several offline and online data transfer scheduling problems and
propose efficient algorithms and techniques for addressing them. In the offline case, I …

In this paper we consider two problems regarding the scheduling of available personnel in
order to perform a given quantity of work, which can be arbitrarily decomposed into a …

Communication flows in distributed systems often present a poor performance, because they
are unaware of each other and end up competing for the same bottleneck resources. A …

As the development of distributed systems progresses, more and more challenges arise and
the need for developing optimized systems and for optimizing existing systems from multiple …

In this paper we tackle several problems regarding efficient data replication in distributed
systems. In the first part, we consider several theoretical offline data replication and reliability …

In this paper I present several novel, efficient, algorithmic techniques for solving some
multidimensional geometric data management and analysis problems. The techniques are …

Many types of distributed systems have been developed and deployed throughout the world
recently, in order to solve various problems or in order to provide novel types of services …

We present the caching-enhanced scalable reliable multicast (CESRM) protocol. CESRM
augments the scalable reliable multicast (SRM) protocol (S. Floyd et al., 1995 and 1997) …
