移动计算中语义缓存的改进研究
ON IMPROVEMENT OF SEMANTIC CACHE IN MOBILE COMPUTING
摘要
Abstract
In existing mobile computing environment,semantic caching lacks the spatial index of location information.In view of this,we propose a quadtree index structure-based semantic caching and its query trimming algorithm,this expands the traditional semantic caching and implements the object-oriented semantic cache.Through simulation experiments,we compare and analyse the performances of the algorithm. Results show that the quadtree semantic cache reduces the average response time,the number of comparisons and the network traffic load.关键词
