A new tuple space structure for tuple space based mobile middleware platforms

Abstract

Tuple space model is a simple and efficient data-driven coordination model, suitable for different mobile middleware platforms. A significant performance factor of this model is tuple space structure. Existing tuple space models have sequential tuple space structure, which works efficiently with tuple-producing primitives. But, tuple-reading and -consuming primitives that drive overall performance of tuple space model, generate substantial overhead with this sequential structure. In this paper, we propose an efficient tuple space structure, which is not only simple, but also improves performance and scalability of tuple space model. We have compared proposed structure with existing ones to show the improvements. Tuple space model with proposed tuple space structure not only preserves the ease of developing mobile applications, but also facilitates performance gain during their execution.
