Sixth IEEE International Symposium on Network Computing and Applications (NCA 2007), 2007 In this paper we present a wide area distributed system using a content-based publish/subscribe communication middleware which can deterministically detect and report failures with respect to timely message delivery and message omission. Our approach does not require external clock synchronization nor does it impose any constraints on the publish ...

Location-based Publish/Subscribe
Fourth IEEE International Symposium on Network Computing and Applications, 2005 This paper introduces the concept of location-based publish/subscribe (LPS), which allows mobile ad hoc applications to anonymously communicate with each other, depending on their locations. With this concept, publish/subscribe topics are typically expressed in a dynamic manner including proximity criteria, e.g., "I subscribe to all events on topic T ...

On adding replies to publish-subscribe [PDF]
Proceedings of the 2007 inaugural international conference on Distributed event-based systems, 2007 Recently, the publish-subscribe communication model has attracted the attention of developers as a viable alternative to traditional communication schemas, like request/reply, for the flexibility it brings to the architecture of distributed applications, by allowing components to be easily added or removed at run-time.

Present NoSQL databases are passive entities, where users proactively access the databases serving requested issued by users. While NoSQL databases are scalable due to their horizontal scale-out designs, data items stored in potentially very large databases are difficult to retrieve in terms of access delay, programmability and usability. In this paper,

Publish/Subscribe in a mobile enviroment
Proceedings of the 2nd ACM international workshop on Data engineering for wireless and mobile access, 2001A publish/subscribe system dynamically routes and delivers events from sources to interested users, and is an extremely useful communication service when it is not clear in advance who needs what information. In this paper we discuss how a publish/subscribe system can be extended to operate in a mobile environment, where events can be generated by ...

Prefix forwarding for publish/subscribe
Proceedings of the 2007 inaugural international conference on Distributed event-based systems, 2007We present a prefix forwarding algorithm for content-based publish/subscribe systems. Our algorithm performs only one content-based match per message regardless of the number of routers (hops) traversed from the source to the destination. Moreover, prefix forwarding preserves the decoupling properties of publish/subscribe system. Prefix forwarding does

Distributed and Anonymous Publish-Subscribe
2013Publish-subscribe is a scheme for distributing information based on interests. While security mechanisms have been added to publish-subscribe, privacy, in particular anonymous communication is hardly considered. We summarize security and privacy requirements for such systems, including an adversary model for privacy.

Pricing in publish/subscribe systems
Proceedings of the 6th international conference on Electronic commerce - ICEC '04, 2004Publish/subscribe systems have gained increasing interest in the past few years. There are many commercial products available today that rely on them directly. However, up to now there has been no discussion about pricing in such systemsWe present a new strategyproof distributed algorithm that calculates the maximum subtree of the broker network and ...

On reliability in publish/subscribe services
Computer Networks, 2013Modern large-scale mission-critical systems demand efficient and robust multi-point data dissemination infrastructures. Since such infrastructures have to exhibit good performance when scaling up the number of interacting entities and managing large amounts of data, publish/subscribe services represent a suitable middleware solution due to their ...
