We consider the approximate consensus problem in a partially connected network of n nodes where at most f nodes may suffer from Byzantine faults. We study under which conditions this problem can be solved using an iterative algorithm. A Byzantine node can equivocate: it may provide different values to its neighbors. To restrict the possibilities of equivocation, the 3-partial multicast primitive is...
In a mobile ad hoc network we consider the problem of designing a reputation system that allows to update and to propagate the computed reputation scores while tolerating Byzantine failures. Each time a correct node uses directly a service, it can determine by itself the quality of service currently provided. This fresh and valid rating information is broadcast immediately to all its current neighbors...
We consider the clock synchronization problem in wireless mobile ad hoc networks in the presence of Byzantine nodes. The communication topology is dynamic: nodes move randomly within a geographical area. We propose a clock synchronization protocol which is based on the linear approximate consensus method. Periodically each correct node broadcasts its current timestamp and gathers the timestamps provided...
Recently, in classical P2P overlay networks, with applying replication technique, a single peer is replaced by a cluster of peers in order to tolerant Byzantine failures. In this paper, a novel robust and secure scheme for storage overlay networks is proposed by applying erasure coding technique to reduce redundancy and enhance privacy protection. For achieving a lightweight data privacy protection,...
In this paper, a new method to use the selective electroless plating on fabric to prepare frequency selective surface (FSS) is presented. Different from other substrates which are compact layers and can form close coatings, the coating on the fabric by this method will form holes and gaps between fibers. The effect of holes and gaps to the transmission of electromagnetic waves was analyzed and results...
