In this paper, we propose to the concept of software-defined networking (SDN) in wireless sensor networks (WSNs) with a structured and hierarchical management. We argue that structured and hierarchical management using SDN promises a solution to some inherent problems in WSN management. Furthermore, we propose a cluster based architecture with multiple base(More)
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)
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)
