Abstract

With the increasing prevalence of ubiquitous computing, the software component allocation while meeting various resources constraints and component interdependence is crucial, which poses many kinds of challenges. This paper mainly presents an adaptive component allocation algorithm in ScudWare middleware for ubiquitous computing, which uses dynamic programming and forward checking methods. We have applied this algorithm to a mobile music space program and made many experiments to test its performance. The contribution of our work is twofold. First, our algorithm considers resources constraints requirement, component interdependence, and component tolerant issues. Second, we put forward a component interdependence graph to describe interdependent relationships between components. As a result, the evaluation of component allocations has showed our method is applicable and scalable.
