Gravity: An Interest-Aware Publish/Subscribe System Based on Structured Overlays

Differential Data Protection for Dynamic Distributed Applications

We present a mechanism for providing differential data protection to publish/subscribe distributed systems, such as those used in peer-to-peer computing, grid environments, and others. This mechanism, termed “security overlays”, incorporates credential-based communication channel creation, subscription and extension. We describe a conceptual model of publish/subscribe services that is made conc...

Opportunistic Overlays: Efficient Content Delivery in Mobile Ad Hoc Networks

Current content-based publish/subscribe systems assume network environments with stable nodes and network topologies. For mobile environments, one resulting problem is a mismatch between static broker topologies and dynamic underlying network topologies. This mismatch will result in inefficiencies in event delivery, especially in mobile ad hoc networks where nodes frequently change their locati...

Semantic Peer-to-Peer Overlays for Publish/Subscribe Networks

Existing publish/subscribe systems suffer from several drawbacks, such as the reliance on a fixed infrastructure of reliable brokers, or the lack of expressiveness of their subscription language. Most importantly, the challenging task of routing messages based on their content remains a complex and time-consuming operation, and often provides results that are just barely better than a simple br...

SDNPS: A Load-Balanced Topic-Based Publish/Subscribe System in Software-Defined Networking

Publish/subscribe systems on the traditional Internet suffer from poor scalability and high delay in the face of the Internet of Things (IoT) environment. Being customizable, the paradigm of software-defined networking (SDN) provides a chance to establish an IoT-specific network. In this paper, we propose an SDN-based publish/subscribe system named SDNPS, which can construct and fine-tune topic...
