摘要

This paper proposed a new system framework to distribute interactive multimedia system on location-based service. Especially, the paper presented a new solution to the three-dimensional indoor positioning technology based on location fingerprint method. In addition, a new three-dimensional positioning algorithm of NNSS-AP-AVG together with the clustering analysis is proposed to improve the accuracy of the positioning algorithm. By using the NNSSAP- AVG algorithm, the paper set up a personalized, distributed and interactive multimedia system, which merging the technology of location -based service together. The results of the designed method demonstrated that the new algorithm based on the location fingerprint is significant, which improves the positioning accuracy and optimizes the positioning performance. Finally, the paper evaluated the designed distribute interactive multimedia system and the results demonstrated that the system can give a better performance based on designed location-based service.
