Clock Synchronization

Publications

The improvements in the quality of oscillators of every day computers change the way we can build accurate but cheap clocks. It is now possible to define a clock with today's PC architecture, accurate enough to be used by a large variety of applications.

IP Traffic Characterization and Modeling

Publications

Backbone traffic has been an intensive topic of research for the past years. While lot of studies have been published, describing traffic, its scaling behavior and proposing models, two directions are still under investigation. The study of wireless traffic and the comparison of its characteristics to the well-known backbone traffic. The definition of simple models, easily usable in practice, that take into account the scaling properties of the observed traffic.

Autoconfiguration for Self-Organized Networks

Publications

With the widespread deployment of wireless technologies, self- organized networks (Ad-Hoc, Sensor or Mesh networks) are supposed to be today's reality. While the basic concepts underlying the network layer of such networks have been defined more than 10 years ago, no leading solution has emerged yet. Taroko is a proposed solution to handle the addressing, locating and routing mechanisms while decoupling identity and address of the nodes. Taroko takes advantages of a hierarchical virtual structure of clusters to define local and distributed network layer mechanisms. This virtual structure is particular description of the underlying topology by means of trellis graphs. The publications associated to this work present a description of Taroko, an analysis of its performance and its ability to handle slow nodes' mobility.
