An Optimal Satisfaction Model for Universal Service Terminal System

The development of mobile communication technologies and smart portable device has great impact on the society, which makes the ubiquitous computing and seamless service come true. However, a major challenge is that how to provide a software platform supporting personalized and context-aware services and applications. Research on universal service terminal (UST) aims at providing light-weight application layer to enable the interconnection between the terminals and providing user with always the best service experience (ABE). In this paper, we propose a dynamic aggregation mechanism, which introduces the multi-objective optimal functions to optimize the user satisfaction. Furthermore, a rapid optimal algorithm based on simulated annealing algorithm is provided to improve the search efficiency.
