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)
With the exponential growth of devices connected to the Internet, security networks as one of the hardest challenge for network managers. Maintaining and securing such large scale and heterogeneous network is a challenging task. In this context, the new networking paradigm, the Software Defined Networking (SDN), introduces many opportunities and provides(More)
CONFIIT (Computation Over Network with Finite number of Independent and Irregular Tasks) is a purely decentralized peer-to-peer middleware 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)
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)
We explain the notion of security architecture for Internet of Things (IoT) based on software-defined networking (SDN). In this context, the SDN-based architecture works with or without infrastructure, that we call SDN-Domain. This work describes the operation of the proposed architecture and summarizes the opportunity to achieve network security in a more(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)
