Mobile situations: Exedrae as stages of gathering in Greek sanctuaries

A Cellular Automaton Based Algorithm for Mobile Sensor Gathering

In this paper we proposed a Cellular Automaton based local algorithm to solve the autonomously sensor gathering problem in Mobile Wireless Sensor Networks (MWSN). In this problem initially the connected mobile sensors deployed in the network and goal is gather all sensors into one location. The sensors decide to move only based on their local information. Cellular Automaton (CA) as dynamical sy...

Gathering Autonomous Mobile Robots

We study the problem of coordinating a set of autonomous mobile robots that can freely move in a two-dimensional plane; in particular, we want them to gather at a point not fixed in advance (GATHERING PROBLEM). We introduce a model of weak robots (decentralized, asynchronous, no common knowledge, no identities, no central coordination, no direct communication, oblivious) which can observe the s...

Gathering Non-oblivious Mobile Robots

We study the Gathering Problem, where we want to gather a set of n autonomous mobile robots at a point in the plane. This point is not fixed in advance. The robots are very weak, in the sense that they have no common coordinate system, no identities, no central coordination, no means of direct communication, and no synchronization. Each robot can only sense the positions of the other robots, pe...

Wait-Free Gathering of Mobile Robots

The problem of gathering multiple mobile robots to a single location, is one of the fundamental problems in distributed coordination between autonomous robots. The problem has been studied and solved even for robots that are anonymous, disoriented, memoryless and operate in the semi-synchronous (ATOM) model. However all known solutions require the robots to be faulty-free except for the results...
