This paper deals with the classical problem of exploring a ring by a cohort of synchronous robots. We focus on the perpetual version of this problem in which it is required that each node of the ring is visited by a robot infinitely often. The challenge in this paper is twofold. First, we assume that the robots evolve in a highly dynamic ring, i.e., edges… (More)

We consider systems made of autonomous mobile robots evolving in highly dynamic discrete environment i.e., graphs where edges may appear and disappear unpredictably without any recurrence, stability, nor periodicity assumption. Robots are uniform (they execute the same algorithm), they are anonymous (they are devoid of any observable ID), they have no means… (More)

In this paper we study the task of approach of two mobile agents having the same limited range of vision and moving asynchronously in the plane. This task consists in getting them in finite time within each other’s range of vision. The agents execute the same deterministic algorithm and are assumed to have a compass showing the cardinal directions as well… (More)

Tolerating byzantine faults on a large scale is a challenge: in particular, Desktop Grid environments sustain large numbers of faults that range from crashes to byzantine faults. Solutions in the literature that address byzantine failures are costly and none of them scales to really large numbers of nodes. This paper proposes to distribute task scheduling… (More)
