Spanning trees help removing cycles and establishing short paths between a given node and the rest of the nodes in a network. In ad hoc mobile computing networks, however, transient node failures occur due to being out of range or powered off. Therefore, we present a self-stabilized distributed algorithm based on homogeneous agents for constructing a random(More)
CONFIIT (Computation Over Network with Finite number of Independent and Irregular Tasks) is a purely decentralized peer-to-peer middle-ware for grid computing. This paper presents CONFIIT main features and how it deals with topology changes and communication faults. To illustrate CONFIIT operation, we demonstrate how the car-sequencing problem can be solved(More)
Among all components of a grid or peer-to-peer application, the resources management is unavoidable. Indeed, new resources like computational power or storage capacity must be quickly and efficiently integrated. This management can be achieved either by a fully centralized way (BOINC) or by a hierarchical way (Globus, DIET). In the latter case, there is a(More)
Network security is in a daily evolving domain. Every day, new attacks, virus or intrusion techniques are released. Hence, network devices, enterprise servers or personal computers are potential targets of these attacks. Current security solutions like firewalls, intrusion detection systems (IDS) and virtual private networks (VPN) are centralized solutions(More)
Summary form only given. The need of computation power increases, and grid computing seems to be a good complement to expensive parallel computers. This paper deals with the evolution of CONFIIT (computation over network with finite number of independent and irregular tasks): a purely decentralized peer to peer middleware for grid computing. We specially(More)
