Cost Model and Adaptive Scheme for Publish/Subscribe Systems on Mobile Grid Environments.

Publish/subscribe model is appropriate in many push based data dissemination applications. This paper presents cost model for publish/subscribe systems, analyze its performance, and compare to other interaction-based models such as the client-server model and the polling model. Based on the cost analysis, we have proposed an adaptive model which can dynamically select an appropriate model for each client independently. [ABSTRACT FROM AUTHOR]
