We develop three functions around the MAC layer: (1) Pseudo broadcast is a technique used to improve throughput of broadcast transmissions in case of congested networks. The mechanism consists in sending a packet in unicast to a station using RTS/CTS. Othe ...
This paper describes a model for simulating crowds of humans in real time. We deal with a hierarchy composed of virtual crowds, groups, and individuals. The groups are the most complex structure that can be controlled in different degrees of autonomy. This ...

The success of new service provision platforms will largely depend on their ability to blend with existing technologies. The advent of Internet telephony, although impressive, is unlikely to make telephone customers suddenly turn in favor of computers. Rat ...
This thesis presents how to visualize a large crowd of virtual human characters in real time on a standard issue personal computer. The virtual humans are distributed into rendering fidelities such that the humans closer to the viewer are detailed and expr ...
The Web services resource framework (WS-RF) and the Web services notification (WS-N) specifications are a crucial component of grid infrastructures. They provide a standardized interface to stateful services so that they can be managed remotely. There are ...
The content of this thesis is two-fold. The first part takes the form of an essay while the second part presents a theoretical project for an architectural installation. Using these two modes as different ways to address similar issues, the present work pr ...

Ad hoc networks are expected to be used in many different situations. A common characteristic among these situations is that the nodes have to cooperate with each other. This problem is particularly crucial, if each node is its own authority. Reckoning the ...

This paper presents the genesis of the Expo.02 robot. RoboX the tour guide robot has been built from the scratch for this project based on the experience of the Autonomous Systems Lab. The production of 11 of those machines has been guaranteed by a spin-of ...
