Previous gossip-based protocols developed for sensor networks or various kinds of P2P networks assume that all processes in a system are interested in all events occurring while communicating among them. Though all query nodes in a large group are running the same application, they might join various multicast groups depending on their interests. However,(More)
Application-level gossip-based broadcast protocols are gaining significant popularity as an interesting alternative to deterministic broadcast algorithms for reliable propagation by providing an attractive tradeoff between reliability and scalability. In addition, many distributed applications require scalable, reliable and causally ordered delivery of(More)
Near Field Communication (NFC) as a promising short range wireless communication technology facilitates mobile phone usage of billions of people throughout the world that offers diverse services ranging from payment and loyalty applications to access keys for offices and houses. And smartphone positioning is an enabling technology used to create new(More)
In this paper, we present a novel method for improving contents recommendation accuracy using LBS-based users viewing path similarity. We have previously presented a user similarity-based contents recommendation algorithm using NFC. However, the existing research might not recommend contents related with exhibits which users did not tag but do like because(More)

When developing networked or distributed systems, network monitoring is becoming an essential facility for controlling and managing their performance or quality of service. Especially as their network rapidly scales up, distributed monitoring schemes based on a hierarchy of monitoring managers has been presented and used. But, failures of some monitoring(More)
