The top-k skyline query in pervasive computing environments
Peng Pan, Yuqing Sun, Qingzhong Li, Zhiyong Chen, Ji Bian · 2009
In pervasive computing environments, more and more applications or platforms based on mobile phone and PDA emerged. People could get what they want from these platforms anywhere. Top-k and skyline query are two methods to satisfy user's preferences. In many situations, we need to combine the two querying technologies to satisfy the user's preferences, which is called top-k skyline query. Based on a given pervasive computing scenario, we formulate a theoretical model for top-k skyline query, describe an algorithm that proceeds the skyline and top-k query synchronously. It shows better performance in experiment than algorithms proposed in.
