This paper proposes a new solution to the problem of self-deploying a network of wireless mobile robots with simultaneous consideration to several criteria, that are, the fault-tolerance (biconnectivity) of the resulting network, its coverage, its diameter, and the quantity of movement required to complete the deployment. These criteria have already been(More)

The notion of distributed MEMS refers to the approach that consists in combining a large number of MEMS. The larger the number of MEMS, the more important the need for distributing the operations of the system (computation, control, etc.) over the individual MEMS. A similar problem is found in today's networks where a large number of communicating devices(More)
Besides the complexity in time or in number of messages, a common approach for analyzing distributed algorithms is to look at their assumptions on the underlying network. This paper focuses on the study of such assumptions in dynamic networks, where the connectivity is expected to change, predictably or not, during the execution. Our main contribution is a(More)
Distributed applications are more and more often developed using object oriented languages even if other programming techniques such as agent-oriented applications [6] or aspect oriented programming [7] emerge. Three de facto standard exist: DCOMTM [4] (Distributed Component Object Model) – MicrosoftTM, CORBA [11] (Common Object Request Broker Architecture)(More)
Till recently it was impossible to have more than one single application running on a smart card. Multiapplication cards, and especially Java Cards, now make it possible to have several applications sharing the same physical piece of plastic. Today, these cards accept to load code only after an authentication. But in the future, the cards will be open an(More)
More and more pieces of hardware are getting connected to the Internet every day. Technologies such as Bluetooth or Wi-FI make this process even faster. All these equipments make sense provided they can communicate with each other. Among the communication paradigms that seem suited for such an environment are mobile codes or mobile agents and/or remote(More)
In this paper, we present a novel approach for the detection and signature extraction for a subclass of polymorphic computer viruses. Our detection scheme offers 0 false negative and a very low false positives detection rate. We use context-free grammars as viral signatures, and design a process able to extract this signature from a single sample of a(More)
