Providing an up-to-date view on dynamically changing data presents difficulties. While several different data-dissemination platforms address the problem, client mobility is still a major challenge. Volatile wireless connections and resource limitations void the attempt to apply the same mechanisms that work in fixed-wired networks. The Rebeca publish—subscribe middleware implementation introduces several concepts for accommodating client mobility in publish—subscribe systems. The authors present experimental results that show how intelligent filtering mechanisms can save network bandwidth inside the infrastructure and at mobile clients while preserving the accuracy of client notifications.
