Sender-based message logging allows each message to be logged in the volatile storage of its corresponding sender. This behavior avoids logging messages on the stable storage and results in lower failure-free overhead than receiver-based message logging. However, in the message logging approach, each process should keep in its limited volatile storage the(More)
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)

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)
In sensor networks, there is a lot of overlapping multicast groups because of many subscribers, associated with their potentially varying specific interests, querying every event to sensors/publishers. Also gossip-based communication protocols are promising as one of potential solutions providing scalability in P(Publish)/ S(Subscribe) paradigm in sensor(More)
In this paper, an atomic mobile agent group communication protocol is designed to have the following beneficial features. The protocol enables each agent to adaptively choose a small number of forwarders among its visiting nodes based on its decision. Also, it replicates paths on which messages should be transmitted to their targeting mobile agents in an(More)

—This paper proposes an atomic mobile agent group communication protocol to achieve all the following requirements existing protocols couldn't address due to their respective limitations. This protocol improves scalability by enabling each mobile agent to choose only a few among its visiting nodes as agent location manager depending on its preferred(More)
