Publish/subscribe systems on node and link error prone mobile environments

Abstract

Publish/subscribe model is appropriate in many push based data dissemination applications such as data dissemination services, information sharing, service discovery, etc. Recently, theses types systems are rapidly adopted in mobile and ubiquitous environment. However, mobile and ubiquitous environments are error prone due to wireless link disconnection, power exhaustion on mobile devices, etc. We analyze performance and effectiveness of publish/subscribe systems on the failure of client and server nodes and disconnection of communication links, which is common in mobile environments. We also perform experiments on our test bed to verify correctness and usefulness of our analysis. © Springer-Verlag Berlin Heidelberg 2005.
