A robust and scalable peer-to-peer publish/subscribe mechanism

In this work a publish/subscribe peer-to-peer mechanism is presented. The purpose of KadScribe is to enable a subscription-based message dissemination mechanism for a large number of participants. The mechanism is intended as a building block for other protocols and applications. Possible applications include SOA messaging, weather information or an instant messaging presence service. The focus is on best-effort, low data rate services. The special challenges of disadvantaged networks such as volatile user behavior, low transmission capacity and faulty network connections are respected. Mechanisms to deal with these challenges in the publish/subscribe system are presented and evaluated in a simulated network environment.
